Perfect fit, easy to install & works! - Itโ€™s hard to go wrong with replacement filters purchased direct from the same source as your fountain and specifically designed for it also.๏Š I have to admit, the first thing that impressed me with the fountain was the filter and it still is. These are NOT the typical light weight, cotton layer, activated-charcoal filter ones associated with most fountains. Weโ€™re talking hard-shell heavy-duty Pur or Brita style construction for your pet fountain which is totally awesome. These are also the only pet fountain filters I have, that are rated to reduce chlorine, lead, and a few other heavy metals which sets these apart. The value pack arrived boxed with 6 filers individually wrapped and accompanied by an instruction/NSF certification sheet. Much like other filters, you do need to soak the filter in water prior to first use (approx. 5 min). These are a perfect fit, easy to install, snap in, and works well. The water quality is always clean and fresh, free of sediment, and odorless. Water gets topped off daily, and changed out bi-monthly. My pets love the fountain so by extension that includes the filter. The filter cost is a little on the pricey side compared to other filter types, but it does filter out more than the others making 24.99 per 6 count or 4.17 each (not including tax) a great price when it guarantees your cats will continue to drink more fresh, clean water. Trust me, cats who drink too little water or become dehydrated are more likely to develop stones and UTIs. Been there, done that, not fun and definitely not cheap! Overall, Iโ€™m happy with the performance of the filters. What can I say? They work!!!!! 5 stars! Review: Great for a single person! - So far, 3 weeks of daily use and I LOVE this Reverse Osmosis machine! It completely takes the chlorine, dull taste out of the tap water. The initial flush took longer than I expected it to, so I was concerned at first: but after following the prompts to refill the tank about 4 times, it finally finished and has been great since. I'd prefer less plastic: but you get what you pay for. For a low budget system, I'm pleased with it. *I would imagine, though, that it wouldn't work well for a family: as a single person, I do refill the tank 2 or 3 times a day (or more). The tank is not very large; about standard pitcher sized. It is also a bit slow to fill a glass, but I've gotten used to it. Probably not great with kids. ## Features - ๐๐ฅ๐ฎ๐  ๐š๐ง๐ ๐ฎ๐ฌ๐ž: Our N1 countertop reverse osmosis system is installation-free and no drilling required.

Since the filter cartridges have been activated, they can work efficiently to achieve optimal filtration performance. 3) The CF filter of the countertop water filtration system features a 6-month lifespan and the MRO filter can last up to 18 months. - ๐‚๐ฅ๐ž๐š๐ง, ๐ฉ๐ฎ๐ซ๐ž-๐ญ๐š๐ฌ๐ญ๐ข๐ง๐  ๐ฐ๐š๐ญ๐ž๐ซ: Hydrate and get fresh, pure water straight from our RO filter for countertop water filtration. Its 2-filter cartridge can eliminate most harmful substances in the water, greatly improving taste. Waste water can be used to water plants, wash dishes, etc. ๐Ÿ’งNote: If L1 is displayed, it means that the TDS in the water is too high, please pour out the remaining water in water tank and add new water. - Please measure your cabinet dimensions to ensure that the cabinet size is larger than the product size.

This is ridiculous nobody can afford this . why?** A: Hi, Thanks for your interest in our filter product. Please note that if you see a red TDS light on the front panel, it does NOT indicate the need of replacing any filter. It means the TDS of the filtered water is rather high now, and you need to empty the external water tank, and fill it with fresh tap water, thank you.

Probably not great with kids. ### โญ After 6 months, it makes a great door stop... *by S***T on April 30, 2025* Total junk. Do not buy. Worked great for about 5-6 months. Afterwards, the display just displays whatever it wants. The letters and lights seem to have no bearing on whether the machine works or not. "L1" or "L2" error keeps displaying over and over again no matter how many times water container is emptied and changed. Unplugging it and plugging it back in forces it to work again. It also takes forever for the water to filter through and it makes funky noises. Taste is ok but filter lights come on within 60-90 days of use. Then, the water container started leaking when it was pulled off for refill or emptying as instructed. It leaked immediately, leaving water all over the counter. Buy at your own risk, but highly recommend looking elsewhere. This unit is not it. ## Frequently Bought Together - Waterdrop N1 Countertop Reverse Osmosis System, 4 Stage Reverse Osmosis Water Filter Countertop, 3:1 Pure to Drain, Reduce PFAS, No Installation Required, WD-N1-W - Waterdrop WD-N1-CF Water Filter, Replacement for N1 Countertop Reverse Osmosis System, 6-Month Lifetime - Waterdrop WD-N1-MRO Filter, Replacement for WD-N1-W Countertop Reverse Osmosis Water Filtration System, 18-Month Lifetime --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/509106394-n1-countertop-reverse-osmosis-system-4-stage-reverse-osmosis-water](https://www.desertcart.co.th/products/509106394-n1-countertop-reverse-osmosis-system-4-stage-reverse-osmosis-water) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
