Do Air Filters Make a Difference? An Expert's Perspective

The right HVAC filters can make the difference between air that is clogged with contaminants and air that is clean and healthy to breathe. Knowing the different types of home air filters is the first step to getting the best indoor air quality you can. Not only does a good air filter improve the air quality, but it also helps reduce odors and make your home a more pleasant place to be. Cheap air filters can only stop the largest particles, such as sand, hair, and dust.

When it comes to the health and comfort of your family, friends, and other guests, it's best to get the most efficient air filter you can afford.

Air filters

can stop biological contaminants, pet dander, dirt, mold spores, and other pollutants. At its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system. This not only improves the air quality inside your home but also protects your HVAC system from potential damage.

Some filters are reusable and washable, but require meticulous maintenance, so they are not usually found in the most effective air purifiers. High-end permanent filters can compete with disposable pleated filters, which are available in a range up to MERV 12 or higher. Regularly replacing your air filter is the best way to keep your HVAC system running. Air purifiers can work to a certain extent, but filtration is much more effective at removing mold in the air.

The value of an electrostatic filter is that it captures smaller particles than a standard washable filter and is completely reusable. Not only can home air filtration be a matter of life and death for those suffering from respiratory conditions, but even those who consider themselves normal and healthy can benefit from cleaner, dust-free and allergen-free air. Some air purifiers use ionizers to help attract particles such as static negative ions that bind to dust and allergens and cause them to be deposited out of the air. This means that in addition to the purchase price of an air purifier, you should also consider operating costs and filter replacement costs.

That's why it's important to use only air filters with the MERV rating recommended by the HVAC system manufacturer. As air moves through the filter, contaminants and particles are captured, and clean air is expelled into the living space. Therefore, while pleats offer thicker filter media, the larger surface area allows more free space for air to pass through. For example, hospitals use filters with a rating of 16, but that's not necessary for your home environment, and using a filter with such a high rating will increase your energy costs. Air purifiers usually consist of a filter or several filters and a fan that draws in and circulates the air.

In addition, there are other things happening in your home that can affect effectiveness such as ventilation (windows open or closed) and new particles that constantly emerge so the air may not be as filtered as claimed. In conclusion, having an efficient air filter is essential for maintaining good indoor air quality (IAQ). Not only does this improve breathing for everyone in your home but it also protects your HVAC system from potential damage. Regularly replacing your filter is key for keeping your system running smoothly while also reducing odors and making your home a more pleasant place to live.
