4 Packs FLT4825 HEPA Replacement Filter B Compatible with AC4825 AC4300 AC4800 AC4900 AC4850, 4 True HEPA Filters & 6 Activated Carbon Pre-Filters

Took exactly 2 minutes to swap these out. Fit perfectly. Arrived fast

The filters last a long time even in a dusty place. I would highly recommend the filtration system to anyone concerned about keeping their environment safe.

A great value for the money I would highly recommend this product.

I have 3 rescue dogs and keep it going in the living room 24/7. You should see the filter every week. It really helps as I have allergies

The fold of the filter is much wider than that of the original manufactures. This allows more particles to pass through. The filters will need to be replaced twice as often, making the cheaper than the OM price irrelevant. I guess you get what you pay for. I will not be purchasing these again.

These are great filters that really help keep our allergies under control.

I bought these to replace the filter in my air purifier because the smoke from the wildfires in the north west were impacting my allergies. These fit great and now my home office is the only place where Im not constantly sniffling. I like having the extra carbon prefilters too, as they make dealing with the hair from my dog and cooking smells so much better.

These filters last a long time and with the replacement filter cover they last even longer.

Does not fit machine properly. Have to push and struggle to make it stay on the machine.
