20x25x1 furnace filters are a common size for residential furnaces. They are typically made of pleated paper or fiberglass and are designed to trap dust, pollen, and other allergens from the air. Furnace filters are an important part of maintaining a healthy indoor environment and should be replaced regularly, typically every 30 to 90 days.

Types of 20x25x1 Furnace Filters

There are several different types of 20x25x1 furnace filters available on the market, each with its own advantages and disadvantages. The most common types include:

  • Pleated paper filters are made of pleated paper and are the most affordable type of furnace filter. They are effective at trapping dust and pollen, but they are not as efficient at trapping smaller particles.
  • Fiberglass filters are made of fiberglass and are more efficient at trapping smaller particles than pleated paper filters. They are also more durable than pleated paper filters, but they are more expensive.
  • Electrostatic filters use an electrostatic charge to trap particles. They are more efficient than pleated paper and fiberglass filters, but they are also more expensive.

MERV Rating

The MERV (Minimum Efficiency Reporting Value) rating is a measure of a furnace filter’s efficiency. The higher the MERV rating, the more efficient the filter is at trapping particles. MERV ratings range from 1 to 20, with higher numbers indicating greater efficiency.

For most residential applications, a MERV rating of 8 to 12 is sufficient. However, if you have allergies or asthma, you may want to consider a filter with a higher MERV rating.
