Filtre à air Filtrete Ultra (Ensemble de 4)

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.

Have used these for 20 years without issue. they are readily available at numerous local stores.

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.
