Fit is hard to find the right size filters for our furnace....so grateful you had them.

Will be perfect for the needs in my home.

For years I have been using these filters and they fit snug. Now 3M has reduced the size and now the filter is loose inside intake and each furnace start and stop the filter makes a noise from the suction pulling filter up when on then falls down when off. Disappointed with companies reducing product quality especially 3M. I have to use duct tape to hold filter in place which is 3M also and it used to stick better for years and now I have to use more tape to hold due to this product quality also reduced.

Supposed to clean all dust, bacteria and viruses from the air. No irs if it really does but can’t hurt to get the best.

First two both said they were locked and I need to contact service. I didn’t want the hustle. Then it paired. A month later I checked it and not working again. Pulled the filter. It needed changing. Like first onr it wouldn’t pair. I am technically advanced. It should not be complicated. The online account only wanted my email, no password. I don’t like that. Good idea that has more work needed
