Making the Right Choice: Selecting an Air Filter for Your Home

When it comes to keeping your home's air clean and free of allergens, dust, and other particles, selecting the right air filter is essential. With so many options available, it can be difficult to know which one is best for your needs. To help you make an informed decision, here is a guide to the different types of filters and what you should consider when choosing one.

Types of Air Filters

The most common type of air filter is the disposable fiberglass filter. These filters are inexpensive and easy to install but don't do a great job at trapping small particles. For this reason, they should be changed on a monthly basis.

HEPA (High-Efficiency Particulate Air) filters are more expensive than fiberglass filters but much better at trapping small particles such as pollen, dust mites, and pet dander. They need to be replaced every three months.

Activated carbon filters use activated charcoal to trap odors and volatile organic compounds (VOCs). These should be changed every six months.

Factors to Consider When Choosing an Air Filter

When selecting an air filter for your home there are several factors that you should take into account:

  • Size: The size of the filter matters as it needs to fit in your HVAC system properly. Make sure you measure the dimensions before purchasing a filter.
  • MERV Rating: The Minimum Efficiency Reporting Value (MERV) rating measures how effective an air filter is at trapping small particles. Look for a filter with a MERV rating of 8 or higher.
  • Cost: Air filters range in price from just a few dollars up to hundreds depending on type and size. Consider your budget when making your selection.

Maintenance Tips

Once you have chosen the right air filter for your home it's important that you maintain it properly. Here are some tips:

  • Check regularly: Inspect your air filter each month so that it isn't clogged or damaged.
  • Change regularly: Replace your air filter every one to six months depending on the type of filter and your home's air quality.
