Originally add one Allen air purifier. We were impressed and bought three more. Definitely helps keep the dust down in the house and helps with the basement furnace fan.
The display lights turn back on mysteriously later after I turn them off! I have tried unplugging the air purifier and then plug it back in hoping this resolves the issue, but the lights once again turn back on later after I turn them off. Your air purifiers are not cheap! This should not happen when pay this much in hopes that you are getting a good quality product! I either want my money back or an air purifier that actually works like it is intended to work! I have bought a lot of your air purifiers and filters and have paid you well! I expect a timely response in hopes that your business likes happy customers!
Well packaged & quick delivery. Solid, quality unit that is always working to clean the air. We have experienced a reduction in sneezing and allergy symptoms with unit in operation in our home.
My wife and I have allergies, and noticed it was difficult to remove cooking odors from our kitchen/great room. Since we purchased our Alen and started using it we have noticed a marked difference in air quality in our home. The unit is as advertised quiet, and seems to be doing the job in cleaning the air in our home. We consider the investment me made in your product worth while.
