I began shopping for an air purifier when I noticed some consistent smog-like airborne particles in my house for several days in a row. Whatever it was wasn't making us sick, but just didn't look good. I chose the Pure Enrichment PureZone Elite 4-in-1 due to the experience we've had with the Mini Portable Air Purifier that we've had for a while now. Anyway, I set the tower purifier up in the room where the "smog" was and let it run for four hours overnight, as well as four more hours the next night. The following morning, the smog was gone! It has remained gone, too, so I am very thankful for that. The unit also looks sleek, and its interface is user-friendly. I'm hoping it lasts for at least the five-year warranty period...it's also nice that the warranty is extended for an additional two years when you register the product.

I bought this purifier because of the Canadian wildfires plaguing northern Ohio this summer of 2023. I have COPD, chronic bronchitis, asthma, pollen allergies and dog allergies. Staying at an rv campground in my 35 foot rv that does have good air conditioning. Campers at campground still have campfires burning during the Canadian wildfire emergency. My negative symptoms that caused me to buy purifier included burning eyes and skin, sinus pain and congestion, headache, runny nose, sore throat, large airway pain, coughing, sneezing and coughing thick phlegm that is yellow, brown, green. The features that attracted me to purchase purifier are the uv sterilizer and ozone generator at a good price.

My rv smells so much better now. The wildfire smoke and campfires outside smell horrible, i do not even want to go outside. II sit in front of the air purifier now when I watch TV, but whole rv smells so much better now. All of my symptoms have improved.

Overall I am Very pleased with the performance of this air purifier. I actually have two, one in my bedroom and of in my living room. I really appreciate the function of when I have it set on the lowest fan speed that allows it to increase speed when it detects a contaminant that needs to be cleared from the air such as when I use my hair spray in the adjoining bathroom to my bedroom. Even though the unit is across the bedroom and my hair spray is fragrance free it still detects in increases speed to clear the chemicals. The same with the one in the living room. One time I burned some food and even though there is a wall between the kitchen and living room the unit kick into a higher speed to help clear the air.

Love this purifier! It filters the air and refreshes the air very quickly. We have a great room that is 18 'x 20' so we put it on high when getting rid of allergens. We have both a dog and cat. We sometimes take it into the bedroom and put it on a lower setting. which is perfect for sleeping, And great for masking unwanted sounds. I do cover the tiny blue lights at night because I like it very dark. Good value for the money as long as the filters stay a reasonable price. I researched a lot of purifiers and I am happy with this one!
