- 400 HEPA Air Purifier Large Room Air Cleaner up to 2,000 Ft² - HEPA CarbonTech Filter up to 500X Stronger - Air Quality Sensor, Auto & Quiet Sleep Modes - Air Purifiers for Large Rooms

Purchased the PuroAir 400 Air Purifier on the 29th and received it today June 2nd. The PuroAir was very easy to set up. Two parts of my home are being remodeled and I have tons of dust. It took PuroAir about 3 hours to go from Red, the worst air quality to Green, the best air quality in my bedroom. The range covered my bedroom, kitchen, and living room. I opened the bathroom door and PuroAir immediately changed to red. This is one of the rooms being remodeled. The sensor changed back to green after 15 minutes. It is also very quiet.

The air purifiers are working great! They are almost silent at low speed and do not intrude on sleep. They are small enuf to fit in a corner without presenting a danger to someone, like me, who trips over their own feet. Do they work? When I moved into the condo there was mold. My nose ran, my eyes itched. and I had a constant stuffed up head.?I I’m allergic to mold. Do I cleaned up all visible mold and ordered the air purifiers. Three weeks later after running one in the bedroom and 1 in living room 24 c7 my symptoms are gone - only return if it’s been raining which for me is norm. So I say they work to clean the air and make breathing easier. I’ll continue to use them as a precaution and also to ward off anything else that’s floating around - like what the cat brings in on his furry coat.

Very good product, keeps the air clear at a minimum cost.

I have one of these air filters on the first floor in a central area and one on the second floor, also in a central area. We live in the country and next door to a farmer. So, we often get a lot of dust when the farmer is harvesting. We also have 14 pet birds, one of which is a Moluccan Cockatoo, that produce a lot of dust. When I dust every 2-3 days, there is always a new layer of dust. My assumption is that this dust is settling from the air. I have had these two air purifiers running on high for a little over 2 weeks, and have noticed no fresh air smell as other reviewers have reported, but have noticed less dust in the air when the sun shines in the front window. When I first set them up, I was surprised the air quality light went immediately to green. Today I checked the filters, after 4 weeks, to see if they collected anything, and they looked as clean and new as the day I started using them. Since I also have a small desktop air filter that collect quite a lot of dust from the air, I am wondering if these air filters are working at all. UPDATE 02/13/2024: I have had these air purifiers running for a month. Considering the amount of dust generated from road dust on a main highway in the country, dust from surrounding farmer's fields, and feather dust from our 14 pet parrots, I don't believe these filters collect much. I have one on the first floor and one one the second floor. On the first floor, the air filter is in the living room that has direct access to the family room where my parrots are out every night for exercise and socializing. We generally get a lot of dust in the family room. Although the living room doesn't get seem to get as dusty and is easy to keep up with a Swiffer Duster, the family room still gets as dusty as ever. When I checked the filter in the living room after a month, there was a light layer of dust that could barely be seen. These filters are supposed to cover 1115 square feet, and our living room is about 300 square feet. Even though the family room is directly connected to the living room with a large arched doorway, I suppose it's possible this filter will cover only one room, and not necessarily the square footage advertised. If this is the case, smaller, less expensive air filters for each room might be more cost effective. UPDATE 04/23/24: We have now had these air filters for over 4 months. They do seem to collect some dust as we have one in the living room and I don't have to dust as often. Personally, I have not noticed any change in the air quality, but that could just be me. As mentioned previously, I have one upstairs near my bedroom door. This one I keep on the auto setting as it usually stays on low. I tried it on the high setting, and even with my bedroom door closed, I can still hear it. I am one that needs silence to sleep, so I keep this one on low. The one in the living room is kept on high in hopes of collecting some of the dust from the family room that is caused by pet birds taken out every evening. One concern I had was the cost of replacement filters. The "genuine" filters cost $75 for 2, but I found compatible filters for $33 on Amazon. In the over 4 months I have had these air filters, the "change filter" light has gone on only once on the unit in the living room. Since it had a coating of only fine dust on it, I vacuumed it to remove the dust. After re-installing this filter and resetting the "change filter" light, it has been working fine. I feel by vacuuming the filters, the life of the filters could be extended to well over 6 months and possibly even a year. This greatly reduces the cost of filter replacement for these air filters. UPDATE 04/12/26: I have had these air filters running 24/7 for about 2 1/2 years. They do help to reduce the dust in the air and reduce dusting requirements, but I don't think they cover 1,000 sq. ft. as advertised. Our living room is 218 sq. ft. It does help to reduce the dust in the air, and it's possible I have been expecting too much from the small air purifier. I am continuing to use it since I believe it helps to clean the air. I hope this review was helpful for you I will update this review if my opinion changes.

I’ve been using the Powerful PuroAir HEPA Air Purifier for several months now—one in my bedroom at home and another in my office at work—and I am truly impressed with its performance. If you're looking for an air purifier that delivers on its promises of cleaner air, this one is a game-changer. Whether you're dealing with allergens, pet dander, or just want a fresher indoor environment, the PuroAir HEPA purifier works wonders. How It’s Helped Me at Home and Work: Bedroom (Home Use) – I suffer from seasonal allergies, and I’ve noticed a significant improvement in my sleep quality since I started using the PuroAir in my bedroom. The air feels noticeably fresher, and I no longer wake up congested in the mornings. I love the quiet operation—it's powerful enough to clean the air without disrupting my sleep. The 3-stage filtration system (Pre-Filter, HEPA Filter, and Activated Carbon Filter) is fantastic at trapping dust, pollen, and even smoke or cooking odors. It's like a breath of fresh air every night. Office (Work Use) – I decided to get a second PuroAir HEPA for my office, and I’m so glad I did. My office is in a busy area with a lot of people and constant air circulation, so the air quality is often less than ideal. Since using the air purifier, I’ve noticed less fatigue, fewer headaches, and clearer breathing while working. The sleek, modern design fits right into my office, and I appreciate how it’s not bulky or distracting. The purifier works quickly and efficiently, so I feel the air quality improving within an hour of turning it on. Key Features I Love: HEPA Filtration Efficiency: The true HEPA filter is incredibly effective at capturing particles as small as 0.3 microns, which means it’s great for allergies, dust, and pet dander. I’ve even noticed fewer dust particles accumulating around the room, which tells me it’s working harder than I expected. Quiet Operation: One of my biggest concerns when buying an air purifier was how noisy it would be. The PuroAir operates so quietly that it’s easy to forget it’s even on. I can keep it running at night without any disruption to my sleep or focus during work hours. Sleek, Modern Design: The design is compact, stylish, and doesn’t take up too much space. It looks great in both my bedroom and office, blending in seamlessly with the decor. The touchscreen controls are intuitive and easy to use, and I love that it has a filter replacement indicator—it makes maintenance so much easier. Air Quality Sensor & Auto Mode: I absolutely love the smart auto mode, which adjusts the fan speed based on the air quality in the room. It’s a great feature that ensures the air purifier is working efficiently without me having to manually adjust the settings all the time. Energy-Efficient & Cost-Effective: I was pleasantly surprised by how energy-efficient the PuroAir is. It’s running 24/7 in both rooms, and my electricity bill hasn’t seen any significant increase. Plus, the filter replacements are reasonably priced, making this a long-term investment for cleaner air. What I Appreciate Most: The smart sensor that adjusts the purifier’s speed based on real-time air quality is a standout feature. I’ve noticed it automatically increases the fan speed when the air quality decreases (for example, after cooking or during high pollen seasons). It's a huge convenience to know that the purifier is always optimizing itself for maximum efficiency. Final Thoughts: The Powerful PuroAir HEPA Air Purifier has transformed the air quality in both my home and office. It’s powerful, effective, and efficient, making it an excellent choice for anyone looking to improve the air they breathe—whether you’re dealing with allergies, smoke, or just want fresher air all around. The added benefit of its quiet operation and sleek design makes it easy to use in any room, without disrupting your day-to-day activities. I’ve been using air purifiers for years, but this one is by far the best. The PuroAir HEPA delivers consistent, high-quality results, and I highly recommend it to anyone who is serious about improving their indoor air quality. If you're considering purchasing an air purifier for your home or office, this is an excellent option. You won't be disappointed!

By far, the best air purifiers I've had so far, I have two other ones that do not perform this well and these do not place dust all over the place either. They have carbon filters with HEPA and my other two are only HEPA, huge difference. They are quiet, relaxing to hear and have several settings. They come with two filters which is a huge plus because filters are expensive.

Easy to setup. Love the different fan levels. It is quiet! Definitely works! So happy that this has made a huge difference with my daughter’s allergies. We ended up buying the two pack one of her room and the living room. Loved it so much and noticed a difference that we got one for our bedroom

I started with 2 of these PuroAir 240's and added a third. Our home air quality has improved considerably plus the amount of dust has decreased dramatically. Noise level is lo especially on the lower settings, which are normal for us and are easy to adjust. The indicator is easy to see, and you know that that the filter is fine.

Best product we have acquired for air purification. Bonus is its control on dust. Wife has minimal coughing with the units capacity to clean the air .we use in our home witch is 1400 sg ft.

It cleans the air, like it should. Very good we have a separate monitor, it does work very well and is noise less.

Worked well to start with then kept cutting out, contacted suppliers but wouldn’t refund as I am in the UK.contacted Amazon and they refunded me

The product is lightweight cheap plastic. The company ship to the UK yet the device requires a voltage step-down unit to cope with the 110V rated USA device. Company either dumb or dishonest. Factor in additional £50-100 for device to step down UK 240V. So far not seen source for replacement HEPA filters on Amazon either.

Facile à utiliser et fonctionne très bien
