MSA3/MSA3S Filter Replacement, Compatible with Membrane Solutions MSA3 and MSA3S Smart Air Purifier, 3-in-1 H13 True HEPA, 2 Pack

I’ve bought this filter 5 times for my air purifier. It does a great job!! It says it should last 6-8 months, depending on your environment. I’ve found I replace it every 3-4 months. I even vacuum it and use it again before purchasing. I mostly use it for removing smells from cooking. I do have one short haired dog. No smokers in my house. I rated it 4 stars because I believe it should last longer. Overall, good filter.

I like my air purifiers. My nights are pretty quiet and clean air helps with my allergies

This product would not work in my MSA3A. It would not power on.

I leave mine on all day so I go thru a filter about every 2 months

Works well for a very long time. My machine runs 24/7. These filters last at least three, if not more months.

Exactly as ordered, fits my home HEPA filter lasts months. Perfect

I would have like instructions, i.e. how often to change the filter, etc.

I ordered these so I could cut a small 2 inch portion to use as a cell phone grip in my Lincoln Navigator. It works super well. My phone stays put in every turn I make. The silicone stayed grippy in negative temps as well.

Great fit, but slow shipping options to Canada
