Membrane Solutions MSA3/MSA3S Genuine Pet Odor Removal Air Purifier Filter Replacement 1 Pack, Upgraded 4-in-1 H13 True HEPA Filter with OdallerPure Technology

These Membrane Solutions air purifier filters are for the Membrane Solutions Purifier ONLY. They are the ONLY ones that should be used with your Membrane Solutions Purifier. Please be careful with other filters that say they are Compatible. I made that mistake and bought compatible filters, they did not work. Membrane filters are excellent filters, the quality, dust removal, functionality and value for the money all gets 5 stars from me. I'm very happy with these filters.

Works well to clean the air in our home and is priced well. I feel better using it with all the air pollution and wildfire smoke lately. Clears the air quickly of smoke and smells.

Immediate relief, air quality much better and helps with odors and allergens. Perfect fit, weight feels like quality. Very quiet. Lots of dust collected over time that would have been breathed in.

UPDATE: The seller reached out and provided a replacement quickly. Much appreciated for the quick service. The filter works great, and my home actually smells better with this one.ORIGINAL:Item came bent and banged up. No protection except the thin cardboard box. It might work okay, but a little more care in shipping is lacking.I've gone through a few of the other filters, and they arrived just fine.

This filter goes with my air purifier and lasts for months. I have a dog who sheds a lot and this helps my son’s allergies.

These do well but are very pricey. I’ve had my unit for 5 years now and still going strong. Does help the air quality. Fits tight.

Easy to replace

Quality filter. Even though a little pricey, the filter lasts 7 - 8 months before it need a reset. I am happy with the product and will continue purchasing as needed.
