HVAC System and Your Allergies

If you are part of the 5.2% of the Peruvian population that suffers from some type of allergy, you’ve come to the right place. As we approach allergy season, it’s time to learn about the relationship between our HVAC system and allergies. Discover with MOTOREX some ways to reduce your chances of having an allergic reaction thanks to your HVAC system.

What’s the connection?

To begin with, we will introduce you to the most common allergens in Peru:

  • Dust mites. Although popular belief says it’s the dust that causes the allergy, the real culprit is the dust mite. These are arachnids, i.e., a family of spiders and ticks that live in mattresses, bookcases, sofas, and other parts of the house.
  • Pollen. It is one of the most common allergens and can be found in plants, flowers, and trees such as cedar, oak, cypress, and sycamores. They have a greater presence in the environment during the flowering season.
  • Mold. Unlike other allergens that are produced in the summer, these microorganisms proliferate in houses permanently, sending their tiny spores into the air.

Since you already know how an HVAC system works, the explanation will be fairly simple. Your equipment moves the air in the room, so when an allergen gets into the room, it spreads throughout the house. What’s more, when you turn on your HVAC after a long time, it’s quite likely that you’ll have some symptoms, either from dust or pollen buildup.

The problem is not your HVAC system, but the poor maintenance that is provided to it, causing allergens to accumulate in or near the equipment. We recommend calling a technician to take a look at it. In case everything is in order, you may be suffering from an allergic reaction due to factors other than your HVAC system.

To reduce the likelihood of allergy symptoms, you can install filters designed to remove pollen and clean the ventilation system to get rid of dust, mold, and pollen buildup.

Get HEPA filters

HEPA filters are the best at filtering out allergens. Some people mistakenly believe that regular filters on their air conditioners and furnaces will protect them from allergens. The truth is that they only filter out large particles of dirt and debris that can damage equipment. In order to remove allergens from the air inside your home, you need high-efficiency air filters to remove most of the harmful airborne agents.

How to choose a HEPA filter

HVAC filters are rated according to the MERV (minimum efficiency reporting value) system. It is based on how well the filter blocks particles of different sizes. It should be noted that ratings range from MERV 1 to MERV 12, so a higher rating is better for removing small particles, such as pollen. Ask your HVAC service provider to install MERV 10 or higher filters to ensure better air filtration.

Don’t forget to replace HEPA filters

For HEPA filters to be effective, they should be changed every two months or more in case you live in an area where pollutants that cause allergic reactions are abundant. In addition, HVAC systems work more efficiently with clean, new filters. A clogged filter can cause your air conditioner to heat.
