Hepa filters
HEPA filters are very effective against dust and other air borne particulates. These filters remove 99.97% of all particles greater than 0.3 micrometer from the air that passes through. HEPA filters can not be washed and must be replaced every 3 months.


I have received my unit back and it works fantastic. I can't believe what a pleasure it has been to use your services. Do you sell refurbished unit as well? I will tell all my friends and family just how satisfied I am with your services as well as your com- munication with the customer throughout the process. Please feel free to use me as a referral any time. I am one very satisfied customer.
