- Is MERV 13 too restrictive for my furnace?
- Most modern residential systems handle MERV 13, but older or undersized blowers can lose airflow. If you have a 1-inch slot and a basic system, check with an HVAC tech before switching from MERV 8.
- How often should I change it?
- Every one to three months, depending on pets, dust and how often the fan runs. The 24-pack covers about two years at monthly changes.
- What does FPR mean?
- FPR is a store rating scale, not an industry standard. FPR 10 roughly corresponds to MERV 13 filtration.
- Does it fit a 24 x 30 x 1 slot?
- Yes, the nominal size is 24 by 30 by 1 inch. Actual thickness is often slightly under 1 inch, which is normal for pleated filters.
- Is this a good price?
- At $348.50 for 24 filters, that is about $14.50 each. That is typical for MERV 13 in bulk, so compare per-filter cost against smaller packs before buying.
- Where is the Simply 24 in x 30 in x 1 in MERV 13 FPR Furnace Air Filter 24-Pack cheapest?
- At The Home Depot, for $348.50, as of our latest check.
