Here in Houston, we know your HVAC system is a vital part of your home- an absolute necessity, given the heat! One of the most important components of your heating or cooling system is the filters it is equipped with. This is because filters greatly determine your home’s indoor air quality (IAQ). Different filters have different capabilities, which is why Air Tech of Houston AC & Plumbing has compiled pros and cons for the different types you might need.
What Is Indoor Air Quality? (IAQ)
According to the EPA, indoor air quality is the air quality within and around buildings and structures. The inside of your home is plagued with multiple pollutants, some you might never have thought about before. Dust, pollen, pet dander and bacteria are just some of the few things that accumulate inside your home that contribute to bad IAQ and poor health. That’s why choosing the right HVAC filter is essential in improving the health of your household.
How Do HVAC Filters Help Improve Your Indoor Air Quality?
You might have heard that HVAC maintenance is essential- especially regularly checking and replacing the filters. This is because filters play a vital role in purifying the air in your home and keeping the HVAC system running properly.
When air is pulled into the HVAC system, it is cooled, filtered, and blown into your ducts. An old filter would result in dirty air circulating in your home, which is detrimental to your health. Other than your personal health, filters also protect your HVAC system.
Types of HVAC Filter
- Most efficient for removing allergens in the air. It is especially recommended for those suffering from asthma or allergies.
- Replacement needed every 2-3 years, competitive longevity compared to other filters.
- To be HEPA certified means the filter has gone through rigorous testing to earn the HEPA title. Only filters that meet their criteria are allowed to be labeled as HEPA.
- Air pollutant removal exceeds 99.97% and has the ability to trap the smallest, finest particles.
- Some HEPA filters are washable, depending on the type you purchase. This allows for a more reusable, cost-effective option.
- When it comes time for you to replace your HEPA filter, inevitably, they will be very pricey!
- Some systems don’t include UV light, which results in less effective bacteria reduction.
- If the system you buy doesn’t come with a carbon-activated filter, removing odors and gasses won’t be effective.
- MERV is a system that rates filters on a scale of 1-20. The higher the number, the better a filter can catch particles in the air.
- When removing odor, fumes, and smoke, MERV filters accomplish this very well.
- For allergen removal, high MERV filters are commonly used.
- If you don’t have your MERV filter maintenance regularly, this will disrupt the HVAC system.
- In order to trap allergens, MERV filters must be rated 11 or higher. Anything lower than an 11 would not be effective.
- The higher a filter is, the more potential it has to affect airflow.
