A:AnswerWe've had ours for almost 3yrs now. Only changed filters 2x. Really depends on how often you use them and how much allergens, etc are in your home. Ie pets, smoking, etc But filters online at bestbuy.
A:AnswerFilter replacement is “B” for this particular model. The germguardian filters go by alpha size. The filter size is listed on the folding flaps of the box and listed in the instruction manual.
A:AnswerJust follow the filter change instruction. I did not change yet but definitely I will change mine every 3 months for the first use. Just imagine how all the dust inside the filter. I dont think the smoke will ruin the purifier. For me? The Air Purifier helps getting rid of the smell, smoke from cooking bbq. I have indoor grill and sometimes I am frying foods. I am amazed how this air purifier helped getting less smell in my house and for a short time the smell is gone. Overall it really helps. I have two of this kind of model, and I have a bigger one same brand. I am planning to get one for our basement.
A:AnswerAll of our filters are HEPA filters which meet the 99.97% fractional efficiency under IEST-RP-CC001.6. The term “True HEPA” is synonymous with “HEPA”.
A:AnswerIt does move air, but not exactly the same as a fan. It pulls the air from the back to the front, and depending on the setting you get some air movement. But if you want to feel air on your face to cool you off in a heat wave, not so much.
