What Does 20x25x4 Air Filter Mean?
The numbers 20x25x4 refer to the filter’s dimensions. The filter is 20 inches long, 25 inches wide, and 4 inches thick. Knowing these dimensions is key because air conditioning systems require filters that match exactly to function efficiently.
When filters don’t fit properly, dust and pollutants can bypass the filter, reducing air quality and potentially harming your HVAC unit.
How Filter Depth Affects Air Quality
One of the main advantages of a 20x25x4 filter is its thickness. Thicker filters trap more contaminants without blocking air circulation excessively. This means they typically need replacement less often, helping you save in the long run.
Benefits of Using a Thicker Air Filter
While 1-inch filters are common, they often need replacement every month. A 4-inch filter, on the other hand can last three to six months, depending on air quality and usage.
Beyond lifespan, thicker filters provide superior filtration. This makes them ideal for families with allergies, pets, or respiratory concerns.
How Often Should You Replace a 20x25x4 Air Filter?
Even the best filter can’t last forever. Experts usually suggest to change your 20x25x4 air filter every three to six months. Still, environments with more dust or pollutants should replace filters more often.
