Review: Take it from a skeptic: After 3.5 years, no regrets! This Coway air purifier is perfect! - We purchased this unit in June 2022, nearly 3.5 years ago. That said, this review is coming from a place of experience with this air purifier. We had just adopted two cats that were born in the bushes outside our home, and I don't particularly care for cats (or more specifically, the smell of cats)! I was concerned about the price of this machine, not because it was crazy expensive compared to other machines that claim to be able to do what this purifier does, but because I didn't want to spend even half of what this thing cost just to keep the house from smelling like cats. On top of that, I didn't want to have to keep buying filters for it. I chose to bite the bullet and purchase this because I figured that if this device could keep the cat smell to a minimum, it would be worth every penny. The recommendation is every year or two, but they are so easy to clean that we were able to extend the filter life quite a bit! The outermost screen filters are quick and easy to get the dust off. It takes about one minute per filter (one on each side) to vacuum off. We clean these filters every 45-60 days. The innermost filters - the big ones with the charcoal - we clean every 12 months. Those take a little longer to clean, but no more than 5 minutes with a vacuum attachment. Everything on this device is easy to remove and replace. Now for the important part... Until just this very week, I have never - and I do mean NEVER - noticed a cat smell in our home. My in-laws have a cat, and they have commented several times over the years how amazing it is that our home never smells like cats - or any odors for that matter! My sister-in-law is allergic to cats but doesn't have any issues at our house. Fast forward to today, I have grown a bit fonder of the cats but still don't like cat smells! I came to desertcart today to purchase my very first set of replacement filters, if that tells you anything about the longevity of these filters! I decided to leave this review just in case anyone else is on the fence about this air purifier. It works. Perfectly. All day. Every day. Additionally, I no longer use expensive HEPA filters in our HVAC system because this purifier takes nearly everything out of the air that those would catch anyway. For anyone who's curious: We have a 1900SF home. I was able to find a great location for this fairly close to the middle of our home so that it purifies the entire house. I go weeks at a time without even realizing this thing is in the room - it just blends in and disappears! If it detects odors, it will speed up for a brief period of time, but almost always runs at the lowest speed - nearly silent. I'm certain that this would even work in larger homes than ours, because in our home it typically only runs at 25%. There are a number of controls so you can adjust the speed, setting, schedule, etc., but we never use them. We just set it and forget it. The power this unit can produce (and the amount of air it can move) is incredible. This purifier brings air in from the sides of the unit and exhausts it out from the top, creating perfect circulation. As an added (undocumented, unsupported) function, anything you place near the top of this unit (potpourri, air diffusers, essential oils, etc.) is quickly dispersed throughout the home.
Review: Big, expensive, works 100% - Yes its big, yes its expensive, but if works, and not just a little. We have an 65 year old house and two large dogs and 2 cats and 2 teenagers so... our house had an "odor" to say the least, also we have large open spaces. Our house is about 4,000 sqft with the great room/kitchen/livingroom being one large continuous space with very tall ceilings. Plus... did I mention our house is old, build in 1959 out of real wood, lathe and plaster, all the good stuff... but after almost 65 years... the good stuff smells... Ok to get to it... this giant air purifier works amazingly well, if you have the space, or you dont care about size, it works better than anything or any other unit we've tried. After 2 days our house has ZERO smell and the air is noticeably clean and dust free. When the dogs are playing rough, or our HVAC kicks on and puts particulate into the air, the display on the unit and indicator light changes if the air is dirty, on the first day, every time the HVAC came on I noticed it would go from 1 or 2 up to 20 or so... it automatically speeds up to clean the air, and now after several days, its only goes up to maybe 4 or 5, umits getting better and better. As mentioned all odor in our entire house (except the teenagers bedrooms, air nothing gonna fix that!) Is GONE. We had a friend who regularly is at our house over last night and she walked in and the first thing she said is "what did you do?, I've never been in your house and it not smell..." thus I decided this product was worthy of writing a review. I was skeptical to spend this much $ on a unit, though we've spent much more when you combine all the others we've tried. Sure they worked to a small degree, or if you were sitting close to them, but this is the first one that has delivered 100% whole-house odor free clean air. Its the sise of a water cooler without the water tank, so keep that in mide, but well worth it to have an odor-free house

### ⭐⭐⭐⭐⭐ 5 yrs strong!!
*by K***Y on January 10, 2026*

I’m going on my 5th year using this device daily, it has rarely ever been turned off. I run it on the setting below the highest, always. I will say it isn’t quiet but it isn’t loud. It creates a nice white noise that is adaptable. I have replaced the filters in it every 9-12 months due to a dust issue living near a lot of farm land, plus I have all hardwood floors, no carpet. I have a small dog in the home who often has company and Im a smoker. Over all I feel like the air is fresh and it helps immensely with dust and dog hair! I never smell my dog or cigarettes in the home. When I come in after work and the house has been closed up all day, I can smell my plugins right outside the front door which is a great thing. I clean the pre-filters weekly and they normally have a good coating of dust and dander that I spray away down the sink. In the summer I sometimes find mosquitoes on the pre-filter! I hit the main filters with the Dyson about once a month as the fine dust does collect and prevent air flow. I have to admit that the original filters did a better job and lasted longer than the off-brand ones that I purchase for about $25 per set but the savings outweigh the loss of quality by far as they are quite comparable with fit and filtration. The sensor is very sensitive to the environmental changes and air flow will increase with change. I love that the front and back are also detachable by sliding upwards and can also be easily removed to be cleaned like the 2 magnetic sides that cover the filters. It has a night mode and a timer feature although I rarely use either. My home is a 1300 sq ft ranch style therefore the layout is somewhat boxy. The device is centrally placed however I believe the lay out of my home would be most benefited from an additional unit as the bedrooms still collect quite a bit of dust but are somewhat partitioned except the doorways. I will definitely purchase another Conway product when my budget allows as I’m very pleased with the reliability and ease of the airmega 400 however it was considered an investment at its price point.
