Some last a bit more than six months and others just four. It depends on the allergens in your air.

This is the third filter Ive used for my air purifier and They usually last a long time. I usually go 7-8 months before the purifier tells me it needs to be changed. The replacement times might be different for each house since dust levels might be different. I live in a very old dust prone house. They do a great job and every so often I vacuum off the dust thats accumulated on the back of the filter just to help make it last longer.

Excellent filter, it comes with a heavy duty internal filter that last 2 to 3 months, and then it has an outside carbon filter that you have to change every 30 days. Anyone that knows anything about carbon filters knows that they don’t last in most environments more than a week to 10 days. It does pick up an incredible amount of dirt and dust. However, you have to change that filter minimum every 30 days, i.e. the charcoal filter. I have another heavy duty filtration unit that I bought during Covid, three times as expensive and about 4 to 5 times better filtration. This filter change out will cost you $40, a more expensive piece of filter change may cost you $50. this is a fairly good filter machine and I would not hesitate to buy it. However, if you’re looking some thing to pick up as much viruses and Covid as possible, this is not the right one however, it helps immensely.

I liked that this one is the real product that actually fit into my air purifier. The price fluctuates every so often. It works as it is supposed to.

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.

This is the only filter for my Germ Guardian HEPA GENUINE Air Purifier. My local Target store never can keep a steady stock. Therefore, I thought of Amazon for my needs. The prize is perfect and better than what Target offer. Thank you Amazon for having this filter in stock. My allergy says, thank you.
