An Overview On 20x25x4-Inch Furnace Filters
Indoor air quality is a hot topic of conversation, and it’s important to do what you can to ensure the air you and your family are breathing is safe and clean. A high-quality HVAC or furnace filter is a good way to ensure you’re removing harmful pollutants and germs out of the air. Furnace filters are designed to remove dust, dirt and debris from the air stream, which also helps to extend the longevity of your furnace’s motor.
There are many varieties of furnace filters, each with advantages and drawbacks. Electrostatic filters are long-lasting and washable. They have an electronic charge and work like a magnet to attract dust particles. Pleated filters increase the furnace area and can capture more particles in the air. They are deeper than other kinds of filters, so it’s best to see whether your furnace can accommodate them.
HEPA filters are popular for air purifiers and vacuums, but they are not as effective for furnaces because they can create a high amount of air flow resistance. They can often reduce air flow in the house, which affects the heating and cooling process. Activated carbon furnace filters absorb chemicals, fumes and odors from the air. They also remove allergens, harmful chemicals and other air pollutants.
The 20x25x4-Inch Furnace Filter Buying Guide
- Furnace filters come in different sizes, such as 20 by 25 by 4 inches. Be sure to check the size that is required by the make and model of your furnace. You will not be able to substitute different sizes of filters, so it’s vital to get the exact size that is required for your furnace.
- Changing or washing your furnace filters on a regular basis is key. Otherwise, you furnace filter cannot do its intended job. Each type of filter typically has a recommendation for when it should be changed or cleaned. As a rule of thumb, plan to replace or wash your furnace filter once every three months.
- In some cases, such as in really hot climates where the HVAC system runs constantly in the summer, you may need to replace or wash your furnace filter more frequently. This also applies to homes which have pets, as their dander and fur can cause furnace filters to need faster replacement.
