Understanding Air Filter Efficiency Ratings

When shopping for air filters, it's essential to understand the efficiency ratings. These ratings determine how well the filters can capture small particles, allergens, and pollutants from the air. Here's what you need to know about air filter efficiency ratings.

MERV or Minimum Efficiency Reporting Value is the most common rating system used for air filters. MERV ratings range from 1 to 20, with higher numbers indicating better filtration. Filters with a MERV rating of 1 to 4 are affordable but only capture larger particles like dust and pollen. Filters with a MERV rating of 5 to 8 are capable of capturing smaller particles like pet dander and hair. However, filters with a higher MERV rating of 9 to 12 are needed to capture viruses, bacteria, and smoke.

A high MERV rating may seem like the best choice, but it's important to understand that the higher rating also means a higher resistance to airflow. This resistance can strain the air system and make it difficult to maintain optimal airflow. It is crucial to check your HVAC system's capacity before buying a high MERV filter to prevent damage to the system.

Air filters with HEPA or High-Efficiency Particulate Air rating are capable of capturing even smaller particles up to 0.3 microns with 99.97% efficiency. These filters are perfect for people with respiratory allergies or immune disorders. However, HEPA filters can only be used with compatible HVAC systems, so it's essential to check the system before buying a HEPA filter.

In conclusion, the MERV rating system is essential when choosing the right air filter for your home. It's important not to overlook the specifications of the HVAC system and the environment where the filter is installed. Understanding efficiency ratings can help prolong the lifespan of your HVAC system and provide excellent air quality for your home.

Different Types of Air Filters

There are several types of air filters available in the market. Each has its own advantages and limitations. Here are some of the most common types:

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.
