I recently purchased the Dyson Purifier/Humidifier with air cooling, and I couldn't be happier with my decision! This product has truly transformed the air quality in my bedroom. First and foremost, the purification features are impressive. The HEPA H13 filter captures 99.97% of allergens and pollutants, so I feel much safer, especially during this intense allergy season. I've noticed a significant reduction in dust, making my bedroom much more of a sanctuary. We have not had the opportunity to really explore the use of the humidifier function as we received during hot humid season, but I would expect it to be a game changer during dry winter months. What I really love is the cooling feature. This summer, it’s been a lifesaver! The air-cooling function is powerful yet gentle, and it helps circulate cool air throughout the room without losing the quality of purified air. My wife would be happy if the bedroom stayed around 40 degrees F...and she's been much happier with this device. The design is typical Dyson: sleek and modern, blending seamlessly with most home décor. I also appreciate the smart controls. The Dyson app allows me to monitor air quality and humidity levels from anywhere, and I can adjust settings with ease. Although the machine operates relatively quietly, and offers more of a "white noise" background, which lends towards restful sleep, we do find that we have to turn TV volume up significantly if we are watching TV (which we shouldn't do in bedroom anyway). It is rather large....stands at 3 ft tall, and honestly, I don't know the area recs that it should cover (my bedroom is approx 350 sq ft)Overall, I highly recommend the Dyson Purifier/Humidifier with air cooling and have been quite pleased (especially the with the cooling!) ... show more

This is a nice unit that looks great and offers solid humidifying and cooling functions. While I haven't noticed a notable difference yet in the air purification aspect after early use, I'm optimistic about its long-term performance. A promising start!

    • A great purifier
Review Image by Victor Rivera Victor Rivera
This is a wonderful air purifier with so many features and benefits that it really pays for its price in no time. The design is beautiful and very elegant compared to the old-fashioned filter that I had for many years. It blends perfectly with my floor design and color. I live in an intersection of two very busy streets and the soot from the street is quite heavy. Daily and constant use of this filter has reduced the soot on all my condo surfaces considerably. There is a lot of humidity where I live so I have no use for the humidifier part, but the HEPA filter is very effective in keeping my condo air breathable. The sound from the unit is quite acceptable as I leave it on high while I work and then reduce it to medium when I return home. The cost of the replacement filter might be an issue, but it should last a minimum of one year and for the benefits I think it is worthwhile, and Dyson is a reliable brand, and I know the replacements will be available when needed. When you add the convenience of the remote and the Dyson App that really allows you to monitor and control the unit it is a win-win deal, and I recommend this unit without hesitation ... show more

    • Auto sense air quality and temp
I’m not sure what comes first the fan, air purifier, humidifier or formaldehyde destroyer. Oh, wait there’s more it also helps remove NO2 also known as nitrogen dioxide. The remote stores magnetically to the top of the fan. I would not be surprised if I missed something else it does. I live along side a major thruway 45 feet away sitting 10 feet lower than the road. Vehicle exhaust fumes can get annoying on hot summer days. I have delt with this for more than 30 years. Why didn’t I get this sooner. The fan speeds range from 1 thru 10 and can be set to auto sense. This fan is very quiet from 1 thru 7. Fan speed level 8 thru 10 is a little louder. Not loud enough that you would have to speak louder to talk over or adjust TV volume. It has oscillation but not by the unit turning back and forth. Instead, it has the front vertical bars that rotate left and right. You can also have it send air to the rear of the fan instead of the front. ... show more

    • Great Multi Function Device with Minor Flaws
The PH2 works efficiently as a purifier and humidifier and the cooling function is helpful during warm afternoons. It looks great in any room and has a user friendly display. The air feels lighter and noticeably cleaner since using it. My only gripe is the noise level on higher settings and the small water tank. Otherwise, it’s reliable and packed with smart features. A worthwhile investment for air conscious households that want more than just purification. ... show more

    • Amazing purifier
This is like the Rolls Royce of air purifiers. I've got alot of different models over the years but this Dyson is just incredible. It's a super solid build with tons of features and a water basin for adding moisture to the air. The remote works great and the fan blows fresh air without much noise. The water basin can be a bit tricky to fill but once you use a pitcher it's a cinch. Not sure about filter life or how long it'll last but for now it's the best purifier I've got. Looks awesome in my living room and works perfectly. ... show more

    • I credible product. Easy to use.worth the price.
Item did as described, works flawlessly, easy to use, simple user interface, DYSON always makes great products in my view, this surpassed my expectations. We used to have a large amount of mold spores ND other contams in out air, now our allergies dont bother us a more inside the house, house members have been sick a lot less, and if we do get sick the symptoms dont seem to last as long. Definitely enhanced the air quality in our home and I will use this forever. ... show more
