Does an Air Conditioner Remove Dust?

In the “On” position, the air conditioner fan constantly circulates air throughout the house (even when the house doesn't need cooling). Air conditioners reduce dust in the house by circulating air through the air filter inside the air conditioner. The air filter removes dust from the air every time air passes through it. Dust accumulates in the air filter and regular washing of the air filter is essential to maintain air filter performance.

The primary purpose of an air conditioner is to cool the air inside your home when the outside temperature is high. You seal all the doors and windows and turn on the AC unit to lower the temperature. The technology inside the device draws in air and returns it to a different temperature. However, there are certain things ACs aren't designed for.

They are not a means of managing the humidification or dehumidification of your home. While they adjust the humidity level a bit, you have little or no control over the degree to which this occurs. Your unit is also not designed to clean air pollution. Although the air conditioner contains an air filter, the air that enters may contain some impurities and contaminants that a standard air filter cannot trap.

While it may seem like a lot is leaking in, in reality, for the most part, it's just a change in temperature. Real air is filtered, but it's probably not enough to keep out the impurities that cause respiratory irritation or an asthma attack, since many of the particles are too small for a standard filter to trap. Air ducts can also have dust and pollen deposited there, waiting for the air conditioner to send them to circulate around your house. It's a common misconception that just because the air is colder, it's cleaner. Cold air certainly feels refreshing, but the infectious particles are so small that they can't be detected simply by breathing.

Any claim that air conditioning can improve indoor air quality on its own has been misled by cold air. Air conditioners cannot and do not purify the air. The air filter located near the return air duct or air controller filters dust, pollen and other allergens. But it's a mistake to think that the air filter is a part of the air conditioner itself, rather air filters are part of the entire HVAC system. Air filters with a higher MERV rating are better able to filter particles and filter finer particles compared to lower MERV ratings. Yes, choosing an appropriate air filter is important, but no, the condenser unit itself does not clean indoor air.

A beautifully designed window AC with the latest environmentally friendly R32 refrigerant gas that works quieter than most other AC systems still draws these impurities into it, but they are often returned to the room a short time later. One of the things you can do to help your central AC remove dust and dirt between cleanings is to change its air filter. What you can do on your part is to clean parts of your central AC unit that you can safely access. No matter what causes your indoor air pollution, you'll want to look for an air purifier to get back on track. Because ACs recycle indoor air without purifying it, dirty air circulating inside further decreases indoor air quality. However, they can remove different contaminants such as pollen and dust from indoor air through their filters. However, if you're not diligent about removing it, you may contact Air Pros about AC repair in Orlando, FL more often. Solutions such as a humidifier, dehumidifier, ERV or HRV for whole home use, improved MERV 13 air filter, air purifier, or indoor air quality monitor will work hand in hand with HVAC systems to improve indoor air quality.

However, when supplemented with additional devices installed directly and working with HVAC system, indoor air quality improves. The ceiling cassette, fan coil unit and air treatment unit can be connected to a duct for outside air to enter.
