- What do MPR 1500 and MERV 12 mean?
- MPR is 3M's own rating for particle capture; MPR 1500 corresponds to MERV 12. MERV 12 captures fine particles such as pollen, dust and pet dander, but it is not a HEPA-grade filter.
- Will this filter fit my furnace?
- It is a nominal 20 x 25 x 1 inch filter, so it fits return grilles and slots sized for that. Measure your existing filter and slot before buying, since actual dimensions can run slightly under nominal.
- How often should I change it?
- Most homes should replace it every 2 to 3 months. Homes with pets, heavy dust or long run times may need a change every month or two.
- Is it better than a basic fiberglass filter?
- Yes for filtration. Fiberglass filters mainly protect equipment; the MPR 1500 also captures fine airborne particles. The trade-off is a higher cost and more frequent changes.
- How does it compare with Filtrete's higher MPR filters?
- The MPR 1900 and 2200 capture more fine particles but restrict airflow more. The MPR 1500 is a middle ground for homes that want better filtration without straining the blower.
- Does it come in a multi-pack?
- It is sold as a 2-pack, so you get two filters per purchase.
