30 in. Haven Coll 500 CFM Ducted Under Cabinet Range Hood, LED, Stainless

Nicest range hood I've ever had! I love the rounded corners; especially nice since this hood extends 22 inches out over the range. I figured I'd bump my head a lot since we had to install it 25" clearance over the range. But so far it's not been a problem. I like that the control panel goes dark when it's turned off. We have a great room floor plan, so having the LED clock blazing out the time all day and night can be annoying. Having a light on each side of the hood is like having a spotlight for each of the front burners (don't much use the back ones). But best of all is the great, wonderful CFM. It really clears out the steam and odors, I mean really, really clears them out. We replaced an over the range microwave, so maybe this is not surprising, but I can't remember any hood in any house (16!) I've ever had being as effective as this hood. I haven't had to use the highest setting, but the noise is fine on the lower settings. It is very heavy, so it took two of us using a cooler as a support to get it installed. The existing duct is 7 inches, so we bought an 8"x7" adapter which worked out well. The cabinet was already reinforced for the microwave, so all we had to do was enlarge the vent opening from a rectangle to a circle. All in all, straightforward to install but taking some strength and maneuvering in tight spaces. Hey, Cosmo, consider a bracket to support the bottom edge. That would be much more useful than the brackets that came with it.

This is a beautiful and clean looking hood that works well once it is installed. Installation was a complete nightmare that took two of us about 8 hours for problem solving the tricky install. We had to add blocks to mount it up, and while the hood is extremely well made, the access to mounting holes is nearly impossible. I searched other reviews here and found one who detailed the exact same situation we encountered and even discovered the same round about solutions that my husband did. Very complicated. Value for money is good, once installed.

I live in an open Living/Dining/Kitchen space. The ceilings are up to 18 ft high. The fan that was installed with the house was a microwave with recirculating the air, not exhausting it outside, which is indicated for this type of building. The cooking oils were all over the ceiling fans. We got this Fan, and had a friend/Contractor install it professionally. It required a 8" hole through the solid foam core panel, and moving the Modular cabinet up about 10 inches or so. We had to purchase an outside wall vent louvered cover. It took two pros 3 hours to prep the holes in the wall and cabinet, Install the Fan, and reinstall the cabinet higher... I am not sure why they did it in that order. Luckily it has a PLUG end, and the microwave I removed was already set up with an outlet in the neighboring cabinet... Very handy. Otherwise I would have had to hire an electrician. The only real problem with installation was the plastic coating on the baffle filters, to protect it from scratching. I went through the Manuel three times looking for what to do with that... If it was supposed to come off. And, when I didn't find it there, I went online to the company site, where all they had was the same manual, without any mention of the plastic. So, in frustration, I copy and pasted the name of the fan with "removing plastic from baffle filters" into my search engine. Lo and behold, there was a VIDEO about removing the plastic from the baffle filters!!! Included in the prattle from the demonstrator was "MAKE SURE YOU REMOVE THE PLASTIC... IT IS VERY IMPORTANT TO REMOVE THE PLASTIC FROM THE BAFFLE FILTERS!!! " "Any damage from not removing it is not the maker's fault"... Blah blah blah. WHY IS THIS NOT IN THE MANUEL??? If it is so darn important... I was 99% sure it should come off, but I wanted to be sure I didn't mess it up. The plastic removes fairly easily once you get it started from the ends. I am extremely pleased with the fan. On low, the microwave is louder! There are 4 fan speeds, on 2, I held some smoldering material some 6" away from the front of the stove. Even smoke curling over top of the front of the hood got sucked back down into the exhaust. On 4, it is STILL not as loud as the "exhaust" on the old Microwave! Totally clears the house of smells! And, I had it placed reasonably high off the cook surface, to allow for no one banging their head, and to put spices on the wall behind the stove... LOVE IT, and it looks great! Very clean lines, nicely rounded corners, and heavy duty Stainless Steel including the impressive filters, the display will turn completely off, and it comes with a remote, which will work to about 20-25 ft. Even the contractor was impressed.

** update**. Well it’s been 6 months and I still love the vent hood. Still a joy to use when cooking. Yes, it’s loud but no louder than any others I have ever used. As I said before, this unit removes stove smell and steam on low better than most do on high. It also has 3 more speeds above that. So per happy... still after 6 months. I was doing a retrofit job on my kitchen that had no external ducting. Was a big project but I am delighted with the results. This unit is powerful. On the low setting it extracts more than a normal stove vent does on high. It can almost suck the food out of the pans on the stove. LOL 😆 Lights are good and focused where they need to be. very hAppy with my purchase. Well boxed and commercial grade. A couple of notes.. I used a reducer to take the vents 6 inch exhaust down to a 4 inch. I also installed a secondary butterfly backdraft stop to insure outside air would not blow back in during light winds. I tested the unit before installation to make sure it was 100% operational. Going down to a 4inch pipe did increase back pressure but unit still works better than any hood I have ever used. Great unit.

After living in a home with the previous owner's microwave combo hood for over 8 years, the filters were very clogged and a lot of residue was seen on both the vents and the exterior of my cooking space. Something more powerful was needed, and CFM along with price was the biggest factor I considered in selecting a new range hood. This product is at the top of the air suction power, and may present some loudness at its highest settings, which are only necessary when the cooking is very messy. Otherwise, I can use it at the 2nd and 3rd settings with ease for sucking all the vapors above the stovetop. The installation on my specific kitchen required some modifications because the cabinet was thicker than the screws provided and the previous range hood/microwave had a rectangular duct. Some extra screws and cutting were in order, but the overall install time was reasonable. Some strength is required due to the weight, but with more than one person and appropriate supporting materials it can be easily installed in <5 hours. The suction power as mentioned before is extraordinary. You can feel the raw power before you connect the duct, and it seems that the "vacuum" power underneath is lacking, but it is still more than my previous hood. The remote works fine and the product has a great steel finish that makes my kitchen look professional. The baffle filters seem to work well and look durable enough for years of use, and hopefully the product keeps my kitchen spiffy for years to come. This is the best range hood for its power at this price, and I would say everyone should be it unless they are willing to fork over >$1000 for similar power at other brands.

Have been using this for over a year so i think i can give a fair review. Overall very happy on how the vent hood perform and how well it looks. However I would like to point out a few points as follow: - At first I really prefer some physical buttons as i was worried that touch screen will get false trigger or non responsive due to it may get wet or greasy but so far I have no issue at all. In fact i fell in love of the touch screen due to it durability and easy to clean - the unit is not exactly 30 inch more like 29.5" but I guess it was stated in the spec. so it is not a flaw or anything but expect there will be some gap left to your uppers. I show them in the pictures which I don't think it affect the looks at all. - The unit is well built and heavy duty. The stainless steel feel thick and all the welds and hems are nicely done. the two fan units inside also looks heavy duty and securely fastened. No rattling or vibration of any sort even at full power - The fan is quite loud but is acceptable and expected I don't used to own a lot of range hood so I can't tell it is above or below the norm. - The suction is very good and I found I usually only need to use up to level 2 most of the time. when cook a steak with lot of oil smoke I may need to crank it up to 3. I usually need to open up the kitchen window to let air in and I can feel a strong breeze from the window with this thing on. - love how sturdy those oil screen are. pain in butt to pull all those blue protective films off. Some of the edges are quite sharp so be careful. - Installation is straight forward BUT: I follow the pattern in the manual to prep. the attachment screws location and it turns out the pattern is wrong. So make sure u just measure the unit's mounting hole instead of following the manual. - The unit stated the exhaust to use 8" pipe but this is not a standard America 8" exhaust size. If you get a normal American 8" ducting or elbow, it WILL NOT FIT. The exhaust pipe coming out from the top of the unit is way under 8". Originally I was planning running rigid ducting from the hood to the wall vent but my plan is foiled because of the non standard outlet size. However, the flex hose which the unit comes with fits perfectly with the supplied hose clamp and the flex hose's OD turns out to fit perfectly into the ID of standard 8" ducting. So this ends up working out for me: I have a standard 8" wall vent and I just stuff the flex hose to wall vent all the way it (up to the outlet at the wall outside). This is not ideal as I really want to use rigid ducting to maximize airflow but due to my run is very short and the hood has a lot of power to spare, it didn't quite affect me. hope this helps

Pros: - Stainless steel finish design that looks fantastic - LED light is bright with just two bulbs. - Noise level is not super silent/quiet, but with 500 CFM or higher I don't know if you can find one that is super quiet. - Smoke suction is really good and does the job. - Not super lightweight but for a dual fan appliance it was not that awkward to install. Cons: - The touch buttons on the control panel is hard to find in the dark. So, if I just wanted to turn on the LED lights from the range hood in the dark, it's not that easy. However, on the other hand I just kind of have a mental memory of where the button could be located on the control panel. I have been able to pretty much turn on the lights when I needed it. - The clock does not display while the fan is running for the range hood. Not a deal breaker, but just would have been nice to have more visual data to see while in use. - The back panel screws, the screws provided and instructed for the back of the range hood, are useless. It is the most confusing and difficult diagram to follow, from an otherwise pretty simple installation. The back screws are there to help hold the range hood while you screw in the top screws. - The screws that goes on the top are the weakest looking screws, but they do the job. They kind of just stick out straight from the top. So if you drill the screws upwards and they poke through the cabinet panel, there are four sharp screws sticking out. Very awkward. Would have been nice to have some kind of end-screw caps to cover them. Summary: I've been using this for a little bit more than a month and have been very impressed. Before this range hood, we had a microwave under the cabinet combo vent appliance. It was one of the worse smoke venting appliance I have ever experienced. The smell of scrambling eggs fills up the entire home. With this Cosmos COS-Q57530, cooking curry, steak and many other food items, the smoke do not go beyond the stove. I have had to use level 2 to cook and nothing higher. The noise level for level 2 fan is not super quiet, but it isn't that crazy either. I can't describe the noise level, but it is better than the over the range (or under the cabinet) microwave vent that was originally installed. Oh the timer to shut off the range hood is pretty awesome, I have learned to use that lately. If I cook something that smells pretty strong, I will set the timer to shut off 5+ minutes (you can configure it for 1 minute or higher). I can go eat and not worry about having to get back up to turn off the range hood. The installation diagram paper that they provided was pretty good, I had to ultimately ignore the back diagram because it just didn't make much sense. I drilled so many holes in the back of the wall and none of them matched up to the actual holes on the range hood. If they were required I would have been really angry. I used a small hand lift to raise the range hood up (don't buy the hand lift they sell here, it's a horrible design). The diagram hole for the power cord is accurate, so don't think drilling a smaller hole will work out (I found out the hard way). I had to widen or cut a circular shape hole since the over the range (under the cabinet) microwave vent had a square vent and Cosmos is a round 8 inch vent. It comes with a flexi-duct adapter, which I plan on replacing because I read that it is not recommended for safety/long term use. I can see that the creases from the flexi-duct could potentially catch grease and build up long term enough to potentially catch fire. Furthermore, the flexi-duct is not smooth, so air travel going through it may just cause more noise compared to a smooth/solid duct. My duct goes straight up in the ceiling so not difficult to swap out. Overall, I do recommend this range hood. I haven't had any issues (yet), but I have read where another customer had the fans stop working after a month or two...? I suppose we shall see, because the previous reviews seem to be good overall. If I run into any major issues, I'll be sure to add it to my review here in the future. I use my range hood every day for slightly over a month and have had no issues with it so far. Update 06/21/2021: Installed this last Oct 2020, and we have been using this on a daily basis (2-3 times per day). No issues up to this day. I have not had to turn the fan on past level 2 (out of maximum of level 4), as an example, for either steaks or curry cooking. Still need to get rid of my flexi-duct, but I have to go and find the right fitting.

There are two different models, the JL is the newest. They use different carbon filters if converting to non-exhaust (in room circulation). So you can't order filters through mfg website until you have product s/n in hand so they can sell correct carbon filter. The actual hood width is 29.5", which matches the template. There should be a slight gap on either side. Mine will be tighter than the 2/5" recommended, more like .25 ". Picture of carbon filter installed prior to install. It will be a pain after as with a 25" gap between stove top & hood and filters being recessed, the stove will need to be removed every time filters need changed unless you think it possible to lay on the stove upside down and manuever within a 25" gap.🤔 Download and print the latest online version of the manual before doing anything else! The packaged one is likely obsolete based on package date. Pictures in product description do not show location of power cord (right side). Ordered a plug to fill previous power hole on left side (once again Amazon). Templates go on with print side against the wood. If not you get outlet hole on wrong side. I cut a 1.5" hole centered for new power cord (measure 2x cut once). The part about bending over excess on template is for top template. Remember there is an extra gap on template edging beyond the printed line take into consideration. The directions only indicate the weight as "heavy" (it is actually 59 lbs and change per TS). Better make sure your cabinet supports are screwed into studs and not just drywall anchors, so your significant other does not end up wearing it, if not I hope your job is good enough to cover alimony & child support 😉. There is no way to use the wall keyholes as designed for a under cabinet install, but you can use the top ones (a must & first point of connection). The packaged manual directed screwing into drywall before top. The new version does a 180. You have to remove stove/oven to install (obviously)& space is a premium so getting holes properly aligned is critical to success. Use the template as a rough only, then measure the crud out of it every which way but loose twice over. Take into account trim and cabinet offsets for reference measurements if not you will pay for it. One support person said some people vent into cabinet (when using carbon filter kit and not exhausting through a wall) and the drawing only shows hole in cabinet bottom, not top. At 500 cfm and nowhere to go expect back pressure, overheated motor, and doors flopping like your cabinet is haunted, not to mention a mini sauna from vented clean steam into cabinet, unless the carbon filter blocks "all" moisture and fills drip pan. Black mold in a cabinet would not be fun. If there is a gap between ceiling and cabinet top, best to cut a hole directly above the first. A 8" hole will not likely be enough for bottom hole if using the keyhole slide method in top ideally 8.5 or slightly more"). They need to relocate exhaust vent in design slightly to compensate for the offsets in my humble opinion. Why you ask? Well with an 8" hole you have exactly .25" clearance between duct and hole (when it is not collapsed) add width of compressed duct plus the 1/2" offset (1/4 all around) to slide top from keyhole to slot (final resting place) and you have a preinstalled duct ramming into a cabinet instead of through a hole with 8"! Bending the duct to try forcing it in is asking for damage to it. Duct must be installed before hood goes up depending on whether your entire cabinet bottom is flush or if you have standoff supports with gap in middle see picture. If there is a gap, there will be no room to attach ring to duct after installing hood. The alternative to a larger hole might be to set up some temporary support to rest the hood on and have someone hold in place while someone else sinks screws into all the predrilled/anchored holes. Picture attached of one concept I may use if run into a duct clearance issue. This is where keeping all that scrape lumber around pays off and you can tell your wife, I told you so. New lumber is not cheap. Also due to weight and only 4 wood screws on top, you are going to want to use the beveled washers on top to disperse the weight to a larger area than screw head. Well because the beveled washers provided are the same size as keyhole or a smidge bigger, when raising the hood over preinserted screws it is unlikely they will drop through keyhole in order to allow sliding but hey maybe not. Just saying pre-fit the beveled washers before getting to far in as it would be irritating to raise it up and not have the washers drop through. You may need to buy your own or plan to insert screws and beveled washers while someone holds up 59lbs who keeps saying hurry up I can't hold much longer then drops it with 2 screws in, ripping out the bottom of your cabinet ouch. The wood screws are designed for the washers so even though no direction in manual provided how to use them, they better be on bottom side of hood when your done. (Think"everything" through before you grab the first tool or pencil or end up measuring everything 4x). Instead of buying an 8" flange to come down from top hole, I bought a 8" louvered & screened vent to point exhaust in direction of my choosing. It is the tightest fit imaginable to get the provided ducting over it, but it can be done and avoids the cost of a flange & is so tight I won't need a band. See pictures ( Amazon is your friend here - struck out at Lowes). Getting top hole aligned with bottom hole is tricky. Take into account the inside cabinet wall side thickness when measuring bottom edge to align top hole as bottom hole won't have the extra material. My top hole kisses (lip locks) the cabinet support at the top. Drill a small test hole from bottom to check saw alignment from top down to make sure you don't cut through a support ledge. You may need to offset slightly to avoid that screw-up. This hood may sit a lot lower than what it replaces. Measure from cab bottom to stove, subtract 10, should be 24-36, if not reconsider your purchase. Still waiting on my hole saw..first one defective arbor pins would not align with saw sent back. Second one discounted "like new" was missing arbor and bit all together. So now after research the correct arbor on order via Amazon from same German mfg. so it should fit. I trust German QC more than some others and leave it at that. Hope you found humor in this review but the installation will be anything but funny if you do not spend the time to triple check centered spacing side to side, hole spacing to back wall and spacing between holes. Wear gloves and use care to prevent dings and scratches, ie don't throw any tools at it while cussing. 😉
