I bought a Air Purifier yesterday. Its brand name is Vicks.
Vicks® True HEPA Air Purifier
* Advance 4-stage HEPA filtration system captures airborne particles and bacteria as small as 0.3 microns, such a Bacteria, Dust, Smoke, Pet Dander
* Four speed Settings include Turbo and quiet settings
* Easy to replace drop-in filter cartridge
* Certified to filter the air in an average size room (12 x 18 feet) up to 5 times per hour
* Ionizer freshens and helps remove particles from room air
* 3 year Warranty
* Uses Kaz Replacement Carbon Pre-Filter CF1 and HEPA Replacement Filter HF130
After these two day’s use, I feel it is good for my home.
It has 4 speed fan. The quiet speed is really quiet.
