Wow! Best air filter we ever have used!

I have asthma so I absolutely need to have home air filters. We were not happy with our older models by another brand, no matter how often we changed the filters. We watched a consumers report of the best home air filters and Honeywell scored above all the other brands in efficiency. We bought this model for our bedroom and it cleans the air so well that our room now smells as clean as a hospital room. I am no longer waking up with sinus headaches or asthma.

Saved my life!!

I had my back yard fenced in so that my German Shepherds could be outdoors more. Thought that would help my allergies.. But I got much worse.I was coughing constantly because the dogs were bringing in dust and pollen from the yard. I have 2 Air genius 5 units. I finally stopped coughing!

Got a second unit

We got our First Air Genius in 2017 during the massive fires in our area. It kept the smoke out of the air in the house and worked great! We have a 20 year old parrot and were concerned about her. It worked so well we bought another for the livingroom and are considering a third for the back of the house. We run them 24/7 cause of our allergies.

Highly Recommended!

I've been using the AirGenius 5 for almost a year now. It makes the air very clean and makes my room very comfortable and free of pollen and allergens. I cleaned the filter today by vacuuming the pre-filter with a brush attachment. It worked very well and I could see the filter getting totally clear of particle dust, etc. I washed the permanent filter and put it out in the sun to dry for awhile and inserted it back into the unit easily. It is great to be able to wash the filter, very ecological! I would highly recommend this air filter to anyone with allergies and to clean the air of smoke.

I've had the the two of them running since receiving them about 1 1/2 weeks ago. I have no complaints, they are relatively quiet. Need to observe them a little longer.

I could not have ordered a better air purifier. Its well-made, looks great and, most importantly, does the job. I breathe better and deeper since the purchase. Why did I wait so long?
