Common questions

Which 14x30x1 should I buy: 1000, 1500 or 1900?

The 14x30x1 Filtrete to buy is the highest rating your system can handle, since higher MERV captures finer particles. The 1900 (MERV 13) filters the finest, the 1500 (MERV 12) sits in the middle, and the 1000 (MERV 11) is the entry option.

Is MERV 13 too high for my system?

MERV 13 is the level the EPA recommends if your system can handle it. The EPA advises choosing a filter as high as your system's fan and filter slot can accommodate. Check your HVAC manual or ask your technician if you're unsure.

How often should you change a 14x30x1 filter?

A 14x30x1 filter should be changed at least every 3 months, according to Filtrete. One 4-pack covers about a year at that interval.
