Blueair 200/300 Series DualProtection Replacement Filter

This review applies to all purchases of this dual filter type. This was my 5th purchase. About the best test for one of these filter types is the "skunk test." We live in a neighborhood with several skunks and they've even sprayed our Golden Retriever. Within roughly two minutes, this filter removes any lingering skunk odor that drifts into the house when the windows are open. A filtration system is only as good as the filters designed for your system. I have tried the so-called "compatible" filters for this system and they do not work as well.

I always order them for the filter!

I have had these for 2 fire seasons, and I'm an asthmatic. The first 2 weeks of new filters and I have zero allergies. They gradually come back, but the air is still clear. Throughout 40 spare the air days of 2020 fire season so far, these babies are filtering and doing their job. We've had heat waves AND unhealthy particulate count for weeks. Which means you can't go outside, you need to keep your home locked up, no open windows. These have enabled me to open my windows and take in cool night air when the particulate count drops to moderate/low unhealthy for sensitive group air quality--yellow/orange >125 when it's unbearably stuffy. I close the windows, and these do the job. They are amazing. The filters are expensive, but I'm going to keep buying them cos I can breathe with no problems. I have 2 of the 205 Blueair units for a 750sf home.

Noticeably cleaner air with the filters. Very easy to take out and replace; takes under 1 minute. Crazy to see how much dust and dirt is accumulated while in use! I live in a city and rely on these for clean air.

I once made the mistake of getting “copy” filters that ended up not comparing at all to the originals and when it comes to my health and what’s important and filtering out what it’s supposed to filter, I don’t want to play around! As expected, these are definitely more expensive, probably more than they need to be, but I will still continue to buy them. That’s the only reason why I gave it four stars as I think that they are sold at very high prices. That being said, trust me whenI say that not all filters are created equal! Same with my Dyson fan purifier -I’m not going to mess around with a knock off that doesn’t have the same quality or materials. Being that it’s summer and fire season I am using the smoke barrier one also in the bedroom which I always use in the larger one in the living room/kitchen area. I have them on 6 mo. subscribe and save.

Been using these filters for the last year + I love them. They work good for smoke too.

The smell is chemical and awful coming off this for more than a week. I ran it in the enclosed patio with the window open but still it was bad. My dog got really, really sick and I suspect it was this but I will never know. He is still getting treatment. I have had many of these filters and they always smell so terrible. Why would the company that KNOWS people who use air purifiers are sensitive--then produce these filters where you have to have this pumped into your air for however long it takes for the chemicals to wear off?

I have been using these for about four years and am very satisfied with the way they work.
