Different Types of Air Filters Available and Their Pros and Cons

When it comes to choosing an air filter for your home, there are several types available. Each type has its own benefits and drawbacks, and it's important to choose the right one based on your individual needs. Here's a breakdown of the most common types of air filters:

1. Fiberglass Filters

Fiberglass filters are the cheapest filters available, but they're not very effective at removing smaller particles from the air. They're typically only designed to remove larger particles like dust and dirt. However, they're still better than having no filter at all, and they're a good option if you're on a tight budget.

2. Pleated Filters

Pleated filters are a step up from fiberglass filters. They're more effective at removing smaller particles from the air, but they're still not as effective as some of the other options available. They're a good option if you want something that's a little better than a fiberglass filter without spending too much money.

3. Electrostatic Filters

Electrostatic filters are more effective at removing smaller particles from the air than both fiberglass and pleated filters. They work by using an electric charge to attract particles, which then stick to the filter. While they're more expensive than fiberglass and pleated filters, they're a good option if you want something that's more effective at removing pollutants from the air.

4. HEPA Filters

HEPA filters are the most effective air filters available. They're designed to remove 99.97% of particles from the air, including pollen, dust, and pet dander. However, they're also the most expensive air filters available. If you have severe allergies or respiratory issues, though, they're definitely worth the investment.

Ultimately, the type of air filter you choose depends on your individual needs and budget. Regardless of which type you choose, make sure you're changing your air filter regularly to keep your home's air clean and healthy.

Air filters are an important, yet often overlooked component of your home's HVAC system. They may look like simple cardboard boxes full of fibers, but they play a huge role in indoor air quality and HVAC performance. Here's a quick look at what these filters do and why they are so essential.

Air filters are made up of spun fiberglass, paper, or cloth enclosed in a cardboard frame. Their purpose is to clean the air that circulates through the HVAC system, trapping and holding dust, dirt, pollen, mold, lint, fibers, and other contaminants. Then, when the air is sent back through the HVAC system after it's been conditioned, the filter removes these particles from the air.

Every single bit of air that heats or cools your home will pass through the air filter, so it's critical that it's always clean. A dirty, clogged filter can cause a number of problems, from reduced airflow to HVAC system damage to higher energy bills. That's why it's important to check and replace your air filters every month. 

Simply hold the filter up to a light source - if you can't see the light through it, it's time for a new one.

Absolutely! Indoor air quality can vary from home to home, but most of us spend around 90% of our time indoors, making it essential to ensure the air in our homes is clean. Pollutants such as particulate matter, formaldehyde, mold, and pollen are all common indoor contaminants.

So, what's the best way to improve the air inside your house? Reducing or removing pollutant sources and ventilating with clean outdoor air are the most effective strategies. However, air filtration can also be used to supplement these measures. Portable air cleaners and HVAC filters can both be used to reduce indoor air pollution and improve air quality.

These devices are designed to filter air in either a single room or throughout the entire house. While they are very useful in removing pollutants from the air, they cannot completely clear it of all contaminants. So, if you're looking to breathe easier, investing in a portable air cleaner and/or upgrading the air filter in your existing HVAC system is a great place to start!

Do you know where to locate air filters in your house? If you have a forced air heating or cooling system, then it's likely that your home has at least one air filter. This filter works to get rid of any airborne particles or debris from the air inside your home. To enjoy better indoor air quality, it's advised to replace your air filter every three months. Though, if your home has numerous occupants or pets, you should check your filter at least once a month. When you can't see through it anymore, it's time for a new one. When replacing your air filter, make sure to use the same model number as the one you just took out.

When you want to find the air handler, you'll need to look for a one to four-inch slot. It should either be covered by a removable lid or a wide-hinged lid. Once you open the lid, you should be able to spot the existing filter. Remove the old filter and insert the new one carefully - the filter should have arrows to help you make sure it's inserted correctly. The arrows should be pointing in the direction of the unit.

Homes with larger systems tend to have more than one air filter. After finding the first one at the air handler, you should see a second filter at the return vent. It will be larger than the regular vents and may either be rectangular or square. You may even find air filters in ceiling or floor return vents.
