- Is MERV 13 too restrictive for my furnace?
- For most modern blowers rated for a 2-inch filter, MERV 13 is fine. If your system is older or already runs hot, check the blower's rated static pressure or step down to MERV 11.
- How often should I change this filter?
- Every 3 months is typical, and the two-pack covers about six months. Change sooner if you have pets, smoke, or heavy dust.
- Does it filter odors or only particles?
- It is a particle filter only. It has no carbon layer, so cooking and pet odors pass through.
- What is the actual size?
- It is a nominal 24x36x2 filter; the true dimensions run slightly under, as with most HVAC filters, so measure your slot before ordering.
- Is $119.98 a good price for the two-pack?
- That is the lowest new price among the two stores listing it as of November 7, 2026, at about $60 per filter. That is in line with other MERV 13 two-packs in this size.
- Can I use it in a 1-inch slot?
- No. This is a 2-inch-deep filter and will not seat in a 1-inch return grille.
