25 Replacement Filter for MA Series 25 Air Purifier S1/W1/B1, 3-in-1 H13 True HEPA Activated Carbon Filter

These are great and I replace often - they are totally grey each time. I mean that’s the air we breathe. Poor lungs. Thankful for these filters.

I found these, they fit and are good to go. The "name brand" was going to cost more than the machine itself - which I found ridiculous!

It arrived quickly and it is as advertised.

Quality is good. Installation is easy. Purchased before and will again.

Well packaged and fit perfectly. As described.

Some other cheap brands have photos you can see through the filter. Not these. These are high quality and work great.

What is there to say. It is an air filter. It works. Good price

This is a nice replacement filter for your MA-25. Getting 4 in the box for this price was a bargain!

I gave this product a try to replace the filters for my Medify MA Air Purifier. The original filters cost me around $122 for two sets of filters, but this brand only costs $55 for two sets. Both have the same specs, both fit perfectly and if this brand truly works as good as the original filters, I will be a customer for life. I am unsure how you prove that these remove 99.99% of the polutants in the air, but I could not prove it with the origina brand either, so c'est la vie. I guess I can maybe update my review at the next filter change in 3 months, and see if the filters are as dirty as the original were?? Cannot beat the price, so I am happy!

is ok thanks

Just like the original! They are awesome!
