How Often Should You Change Your Air Filter?

The air filter should be replaced at least once per year. But how often? The frequency will depend on the area where you live. People living in urban areas might need to change their filters more frequently than those who live in desert climates. So what are the best options from www.amazon.com/BNX-20x20x1-MERV-Filter-Pack/dp/B09XC3RQ3J?


Low-efficiency particulate air (HEPA)

HEPA filters are designed to trap particles in the air that are smaller than 0.3 micrometers. Its ability to trap larger particles can be explained by the principle of diffusion. However, smaller particles can be caught through the process called inertial impaction. Particles with a diameter of less than 0.3 micrometers can’t pass through the filter, which is why they hit the fibers. These particles bounce off other molecules when they hit the fibers. This principle is known as Brownian movement.

HEPA and ULPA are two types HEPA filters. ULPA filters are smaller and have smaller surface areas. However, they are more expensive. ULPA filters need a more powerful blower which can increase operational costs and initial costs. HEPA filters are the most cost-effective choice for most biological applications and are a good option for semiconductor manufacturers. Both types of filters have their disadvantages.

Pleated paper

A pleated paper air filter is a common component. These filters can capture small dust particles of 50 to 100 um diameter. Silicon oxide, a substance with a hardness of seven on the Mohs scale, is used to make them. These filters have two stages. The inertial filter retains large dust particles and the pleated filter paper smaller ones. The size of the particles is important for determining the effectiveness of the filter.

Air filters come in many shapes and sizes and vary greatly in their effectiveness. The most common type is the pleated-paper air filter. These filters are the cheapest and easiest to replace.

Washable electrostatic

If you don’t require a high MERV rating from your regular HVAC filter, a washable electrostatic filter might be the best choice. These filters become less effective as they get dirty. It is important to clean your filter regularly, at least every two to four week. However, you may have to buy new filters every four to six weeks, so the filter might not last as long.

While it is easy to clean a regular air filter, electrostatic filters should not be washed in a bathtub or sink. The pressure created by water is not sufficient to remove particles from the filter. You should clean the electrostatic air filter by using a cleaning solution a few times a year. After cleaning the filter, rinse it with clean water. Next, insert the filter into your HVAC system. This will help to keep the filter fresh and clean.


While most people think of air filters as black boxes, the truth is that they’re made of continuous glass fibers. These filters can remove some airborne toxins but they are not as effective as pleated filters. A fiberglass air filter only filters out larger particles and does nothing to block the smaller ones. Fiberglass filters can be compared to a paper bag. They do little to improve indoor air quality. Fiberglass air filters allow for greater airflow than pleated filters. They are therefore the most preferred choice.

A fiberglass air filter has another advantage: it is very affordable. Fiberglass air filters can capture larger debris and not clog the unit’s airflow, which is why it is difficult to find high quality filters at an affordable price. They do have some drawbacks. A fiberglass filter that has a MERV rating below 13 is not capable of removing small particles such as mold particulates. This means that it should be replaced every 30 days.
