Can I use 20x25x5 instead of 20x25x4?
No, the 20x25x5 is an inch wider than the other one and would not fit in the slot made for the 20x25x4. The reverse may work, but would likely allow too much air leakage around the filter.
Is a thicker air filter better?
Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. That means it’s better for you and for your heating, ventilating, and air conditioning (HVAC) system.
Are 4-inch air filters better than 1 inch?

Can I use a 1-inch filter instead of 2?
The higher the MERV rating, the better the filter is at stopping the particles. This means that a 1-inch filter with a high MERV rating could work just as well as a 2-inch filter with the same rating. Most 1-inch filters are available in MERV ratings 1 to 12.
Can I put a thinner filter in my furnace?
While a 4-inch-thick filter is more efficient than a 1-inch filter, the right size depends on your furnace. If you measure the filter slot, and it’s large enough to accommodate the thicker filter, then you can use it. However, if the slot is less than 4 inches wide, you’re stuck with using that thickness.
