How to Optimize Performance with a 20x20x1 Air Filter

When it comes to keeping your home's heating and air conditioning systems running smoothly and efficiently, the size of the filter is an important factor. A 1-inch filter with less surface area will clog quickly and need to be replaced more often than a thicker filter. The combination of a thin air filter with a high MERV rate can also restrict airflow, leading to decreased efficiency and excessive wear and tear. The EPA recommends a MERV 6 rating as the level that begins to protect air quality, so MERV 8 is a good minimum level for an air filter if you want to start protecting air quality.

A minimum of MERV 11 is generally recommended for allergy sufferers, while MERV 13 is typically found in high-end residential areas, hospital common areas, and high-end commercial buildings that are LEED certified. A MERV 13 20 x 20 x 1 air filter is considered an excellent air filter for allergies. If the air filter is too small, dust and other contaminants will flow around the filter and enter the house. If it's too big, it just won't fit at all and you'll be left with unfiltered air until you get a filter that's the right size. Experts suggest changing them once every 30 days if the air filter is made of fiberglass filters, which are of relatively poor quality.

On the other hand, expensive pleated filters can work well if replaced once every three to six months. When it comes to keeping your air filter in top condition, it's essential to take care of it properly. Washable filters should be cleaned once a month, as ignoring them can restrict airflow due to the accumulation of dirt in the filter. Sign up for monthly reminders about filter replacement, tips for maintaining indoor air quality, and exclusive discount offers. Like length and width, thickness is an important part of the furnace filter size and its proper fit to optimize performance. If you notice dust on the surface of the filter or if the system isn't working as efficiently as it should, it may be time to install a new one.

Even if you live in a mild climate with excellent air quality, there's another important reason to change your boiler filter, as recommended. Because many very fine allergens, such as pollen and pet dander, can cause allergies, this filter is the best choice for allergy sufferers. It is also the best option for eliminating other air contaminants that can affect the health of all family members. When it comes to replacing filters, many contractors use a cheap flat panel air filter with no MERV rating or with a very low MERV rating. Instead of going off schedule, here are some signs and special considerations to help you know when it's time to change your oven filter:

  • If you try to use a 4-inch-thick air filter for a system designed for a 1-inch-thick filter, the efficiency will be worse.
  • If you want your central air system to operate smoothly and efficiently, it's important to regularly service your 20x20x1 air filter.
Check out these simple steps you can take to protect your family's air quality and detoxify your home:
  • Replace your furnace filters regularly.
  • Clean washable filters once a month.
  • Sign up for monthly reminders about filter replacement.
You may not have realized that the furnace filter needs to be changed because furnace filters are not necessary in every air conditioning system. But if you want your system to run smoothly and efficiently while protecting your family's health from allergens and other contaminants in the air, then changing your 20x20x1 air filter regularly is essential.
