Air Purifiers for Home Large Room Up to 2390 ft² with PM 2.5 Display Air Quality Sensor, DBFIT H13 HEPA Air Purifier with Washable Filter, Auto Mode, Air Cleaner for Smoke Dust Pollen Pets Hair Odor

This is a quality unit, that really moves air around. My coughing each morning has virtually disappeared after a couple of days running. I did a test where I lit a candle in the room, and the reading went up on air quality almost immediately. Works great when burning a fire in the fireplace and you get that down draft that puts smoke back in the room. It appears that the outside filter is washable which should save on replacement. Definitely glad I purchased this one.

So far we've really liked this. It's quiet at night and even pretty quiet on the low setting. It helps keep down the smell of cat litter and the filters are really easy to clean.

Quite running, visual indication of air quality, works well in 3 to 4 regular size rooms. Would purchase again.

It does the job. Too loud , night time i need to turn it off

I have about a 970 square ft apartment and I put one day while it did work I think if you only have one you have to put it on max. So I bought another and put it on the opposite end of the living room both on level II. That's when I felt the current of air circulating around the house. It was soo good I bought another for the bedroom also set on level II. I can feel the air moving throughout my house and there isn't any stale air. No stuffy nose, no noticeable build up of dust on desk and nor do I see the dust and particulates in the air. Great machine!

I've had a few air purifiers and this one is for sure my favorite. Easy to use , you can clean the filter and it's quiet night setting is nice.

I have a few different types of air purifier units with air quality indicators, but this model is the best I have used to date. My daughter and I have a lot of allergies and sensitivity to air pollutants, and we live in a semi private apartment unit. We occasionally get smokers living behind our unit, but the upper attic vent space allows secondhand smoke exposure. I run H14 purifiers in our bedrooms and got this larger one for central placement in the main living area. It's probably overkill for the less than 900sq ft apartment, but I can't control what happens at the apartments behind us, and I need to make sure our house is as free of air pollutants as possible.Our typical air quality indicator has been really good, usually 1-5ppm and the unit runs quietly on minimum speed, as I run multiple units throughout because HVAC airflow and doors can impact how much these run in auto modes. This model, the fan speed increases quickly once the air quality indicator hits a caution range. I had spilled oil on my stove burner and didn't get it cleaned off completely, and even though there was no visible smoke but a scent starting to noticeable, I heard the air purifier kick into high speed. I checked the air quality and it was at orange, about 120ppm, but was coming down quickly. I snapped a couple pictures 3 minutes apart to show how quickly it filtered the air from smoke of cooking oil burning. This unit was also about the same cost as the H14 purifiers I purchased, but those lack the air quality value and only have a colored indicator light.

It came in quick and work as they should.
