HoneywellHFD280 Compact Air Genius 4 Air Purifier with Permanent Washable Filter, Medium Rooms (150 sq. ft.), Black

The Honeywell HFD series air cleaners are the best on the market with a permanent filter. I own three different models and they are all reliably outstanding - quiet, effective and energy-efficient. This model is the best-in-class filter for small rooms with a permanent filter.

We bought this exact model before for our sons room. Turned out he got allergy related asthma and his nights were horrible. So I had to try it. He sleeps with it right next to his bed on the 2. setting. I guess it’s a nice white noise also. The sleep setting is very quiet though.At daytime it’s on the highest setting. We had to clean the filter once and it is so easy. Just rinse it in lukewarm water with a little bit of dish soap and let the filter dry.There was a lot of dirt in the water and our son got better and was able to sleep without his asthma spray again.Now we bought a second one for the master. It’s oscillating but you can stop that and have it blow in only one direction. I would recommend it for bedrooms. For the living room we have a bigger model.

Have it on most of the time. I at least feel less congested in the morning and let sneezy in general. In an apartment with sensitive smoke alarms, this does make a difference when cooking. I wish I was convinced it's moving more air, but it seems to be doing a good job for the space. The fans are pretty quiet, not silent, but the oscillating motor is getting loud. Going to try and keyboard clean it. I've also felt the need to clean the filter a few times cause it was so built up (good it's getting that out of the air) but it's still never told me to yet.

I was pleased with this air filter, however Amazon's website says it comes with a remote and it does not. Will keep it anyway, great quality & I love the double fans with oscillating setting. Amazon needs to correct the listing.TY, Lisa

I like that I can wash filters and its very quiet.

I really liked this air cleaner. It did a good job and the sleep mode was nice and quiet. It also was easy to clean. Sadly, after less than two years, it has quit. The problem started with all four settings going up to the same high speed - probably higher than the highest, actually. Now it will suddenly just quit running.

It's crazy to think, but it's absolutely true that this air purifier has been life changing not only for myself but also my son.My entire life, I've been breathing through one nostril. My son too is always congested. Our home is spotlessly clean. Within a week of purchasing this purifier, (and I do run it with the charcoal filter) both my son and I have been able to breathe freely through both nostrils. That's not just a matter of convenience, my running and stamina have improved and as proof my VO2 level (volumetric oxygen my lungs can absorb) from my fitness tracker has increased by 10 percent.It all sounds too good to be true, but if you've been on the border trying to decide, just do it.I would not buy another machine because this has a washable filter, and the regular fan speed consumes 4 watts, dleep 2 watts, so it really costs nothing to run versus other machines that you have to buy expensive filters and consume 10 to 15 times more electricity multiplied by 24/7/365.If there's something I'd change on this machine as a manufacturer, I would have a memory setting for the last fan speed before powering off and get rid of the useless brightness function and just supply dim lights.Relax. Breathe in. Breathe out. Enjoy your new life.
