Winix C535 True HEPA Air Cleaner with PlasmaWave Technology
  • I’ve been using it for under two weeks, and I’m down to one pill, I no longer wake up wheezing, the chronic scratchy throat that I developed over the last 4 months is gone, I can take a deep breath withought tightness, and I haven’t had to use my rescue inhaler at all.
  • The air in my room feels much more fresh and any breathing problems I had have gotten better since setting up the Winix.
  • Good air cleaner, works better on higher setting. I have birds and it is helping to clean their dander.
  • I've been very pleased. We have 3 dogs, 2 cats, and 4 people; that's a lot of dust production. I've not been shocked by the amount of particles in the filter, just kind of worried we went so long without an air filter. Vast improvement.
  • Unlike the previous version where each speed level was incrementally louder, this version is either silent or turbo--very little in between. Not good for using as white noise
  • The first 3 fan settings are only subtly different. The 4th fan setting sounds like a jet taking off. A setting somewhere in the middle would be much preferred.
Winix C555 Air Cleaner Features Smart Sensors
  • Works amazing ! Love this here’s a picture of before and after .
  • It is great for a noise maker too for condo or apartment living . We are clean people and look how much dust in before and after yuck
  • It’s now six months later and I can truly say this has made a huge difference for me. My allergy systems were way less severe, not one asthma attack. It has made a measurable difference in my quality of life.
  • This air purifier is powerful yet quiet and the auto setting works well. It's light enough to carry but would benefit from a handle! I could have used a second one for upstairs, but I couldn't justify the cost of two when I was unsure of it's value.
  • Worked fairly well for the first month. I didn't really notice a significant change in air quality. But after a month, the unit would shut off completely every couple of days (I don't think the cat learned how to press the power button).

What customers say about "Features"
Winix C535 True HEPA Air Cleaner with PlasmaWave Technology
  • High tech! It sense that my sister has sprayed peppermint in the room. I like the fact that i can set a timer or use the remote. Its very quiet too.
  • First off I love the sleek design, and its functions are so simple, comes with extra filters that could last 2 years.
  • This is a good product for th money. Easy to get going and program several fan settings. Filters are easy to access and clean or replace.
  • It's also nice and quiet on the two lowest speed settings. And can be in a bedroom without the worry of preventing someone from getting to sleep.
  • Unlike the earlier model, it has a pre-filter to catch the larger particles. And the pre-filter can easily be vacuumed or washed.
  • It's covered with bright LED lights that can't be dimmed unless in silent mode. This may be fine for some people but I saw this model as a downgrade from the previous version.
  • Every time you turn it on and off it plays an annoying loud tone that drives me crazy.
Winix C555 Air Cleaner Features Smart Sensors
  • I have it in the bedroom and after just a day noticed a big difference. Love the auto and turbo features.
  • I have had it for almost a week now. I LOVE IT! It's quiet unless on turbo. Turbo sounds like a window air conditioner but I can still hear my tv just fine.
  • The auto and sleep settings are nice. But i just leave it on Fan speed 2. Very happy with it. A nice clean smell and removes the smoke.
  • The sound of the heater is louder than the sound of this air purifier. Realibility can not be judged, since I have the product for a too short time.
  • I don't find it noisy. It makes some noise, but there are different settings if you need super-quiet. Remember, this white noise actually helps people sleep.
