Is It Possible To Install A HEPA Filter On An HVAC System?

HEPA filter… what is it? A help or just a hype?

So, you've central heating and air systems installed in your house. But you are concerned about stale air creating lingering odor and an unpleasant feeling in the environment? You must be. Whether you agree or not… but the chances of exposure to polluted air indoor are higher than in outdoor spaces. Not to mention, the indoor air is not circulated as much as outdoor space, and uncountable airborne contaminants thrive inside.

Well, that’s not your fault… air is hard to clean.

Since the level of air pollution is increasing day by day it has become pretty difficult to breathe in pure air. But don’t lose hope – there is a way out.

Have you tried installing filtration systems? Here we are talking about HEPA furnace filters. Yes! the HEPA filter maintains good indoor air quality while protecting you from breathing in dust, pet dander, bacteria, and mold spores that ultimately trigger asthma or worse.

It is built up with resistors, capacitors, inductors, like components and requires voltage and current to run.

You must have heard about HEPA filters for home air conditioning and HEPA requirements – it is an effective solution to cleanse the air. But that's not it, if you want to know more about HEPA air filters keep on reading we will disclose some amazing facts about it. But before that, let's drive in deep and explore…

What is a HEPA Filter?

High-Efficiency Particulate Air filters or HEPA systems are designed to purify the air. These filters can help to refresh stale air - reducing the risk of health problems triggered by indoor pollutants, causing respiratory infections, neurological problems, and exacerbating asthma symptoms.


Air purifiers of high quality remove a variety of indoor air pollutants while keeping the environment healthy – just give it a try.

Reasons Why My AC is Tripping Circuit Breaker?

HEPA furnace filters are used in situations where contaminants must be captured on the first pass. In a hospital, for example, you wouldn't want viruses moving in the air; therefore HEPA filtration would almost certainly be installed. Using a dense mat of fibers placed in a precise pattern, HEPA filters can catch up to 99.7% of all pollutants 0.3 microns or larger

Some particles stick to the fiber naturally when they hit - others get trapped by the curved shapes of the filter. Above and beyond, when the remaining specks strike with gas molecules in the filter, they get trapped. This high rate of particle capture comes at a price. HEPA filters are more airflow resistant than MERV filters This means that the blower in your HVAC system needs to work harder to push air through the filter, which uses more energy.

Yes! You read that right… HEPA requirements are different.

HEPA filters are thick and might hinder air flow in home comfort systems and you know why? Due to their high filtering capacity. Call a heating and cooling specialist like Calwest Refrigeration before installing a new furnace to avoid damaging it.

Can You Use HEPA Filters In Your HVAC System?

Wait! What is HVAC system??? The heating and cooling system, sometimes known as HVAC, is an important component of residential and commercial building interiors. It is now considered normal in new constructions and is primarily responsible for maintaining a comfortable atmosphere in living areas.

Don’t stop reading… we have a lot more information for you!

Airborne bacteria, dust mites, pet dander, tobacco smoke, carbon dioxide, and pollen are all eliminated by the HVAC system. Not just this, the units pull out stale and heated air while replacing it with fresh and cool air – you must be aware of this process "ventilation".

You'd probably have trouble getting enough air out of your vents if you tried to install a HEPA filter for home air c in your furnace. The blower motor in your furnace was not designed to run with such a deep filter.

HEPA filters are thick, by thick we mean… too thick.

Most of the HVAC systems are crafted to hold a much thinner air filter as compared to HEPA filter - which typically measures between five and eight inches in thickness. As a result, installing a HEPA filter necessitates modifying the filter housing, which might be costly.

HEPA filters can put a strain on HVAC systems as the systems don't have the power to move air across something as thick as a HEPA filter. Because most residential HVAC systems lack the strength to drive air past something as thick as a HEPA filter, the design flaw can put a load on your HVAC system. As a result, the airflow is restricted, forcing the system to work harder to achieve the desired temperature, increasing wear and tear while also consuming more electricity.

What to Look for in a HEPA Filter?

Well, there are some different styles that work perfectly well with an HVAC system – media air cleansers, HEPA filtration, and air filtration systems.

With 99.97 percent efficiency for contaminants down to.3 millimeters, a HEPA filtration system is the most effective. A pre-filter for large particles, a MERV 17 filter for residual pollutants, and a carbon filter for odors are all common features of these filtration systems.

Besides, air purification systems are a total package - A hospital-grade MERV 16 filter, germicidal lamps, and carbon filters are typically included in air filtration systems. The filter is included in a media air cleaner, and it may also have carbon filtration choices.

Besides, some of the units are designed to work with specific brands whereas others are completely universal. But you don't have to worry about it… specialists can help you determine what best suit your needs.

When purchasing a filtration system for your household, consider the following features:

  • Filtration to hospital standards (MERV 16 and higher).
  • Pollutants, bioaerosols, and smells are trapped.
  • Compatible with smart thermostats.
  • Filters your entire house, not just a room.
  • It does not produce ozone, which can cause damage to the lungs.

Take Away…

When purchasing HEPA filters for home air conditioning, keep in mind that they should be compatible with your HVAC system. Not only this, purchase a device based on the size of your room and filtering ability.

Due to a lack of airflow in most homes, air purifiers are very popular. Although they aid in the reduction of indoor pollution, their filters have a limit. Some filters may last 2 to 3 months, while others can last a year. However, if you really want to maintain a good indoor environment monitor the air filter indicator to make sure you change filters at an appropriate time

Besides, if you want the air quality of your home to be improved Calwest Refrigeration is here to assist with no obligation home comfort assessment.
