Your HVAC Can Help Reduce Allergens

indoor air quality

Many homeowners think of things like replacing the filter in their HVAC system to reduce the spread of allergens throughout the home, but there are actually several different ways that the HVAC system can be used to reduce asthma and allergy symptoms.

Certainly the filter is the first line of defense against indoor air pollutants so it’s important to replace it regularly and buy a quality filter.  The professionals at Diamond Heating and Cooling can recommend one based on your specific situation, but in general it’s recommended to look for one with a higher MERV rating.  This rating will range from 1-20 with a higher number indicating a higher level of filtration.  It’s also important to choose a high-efficiency filter that is designed to help reduce allergens.  Most high-efficiency filters are rated from 14-16, and are designed to remove small particles from the air. The highest rated filters are HEPA filters which are rated from 17-20 however you’ll want to check with an HVAC technician though before installing a HEPA filter as they are only intended to be used on HVAC systems that can handle the additional stress that this type of filter will put on it.

Looking to do more than just change the filter?  There are some accessory items that can be added to your HVAC system to further improve the indoor air quality.  The most common first addition is an air purifier.  A whole-home air purifier is highly recommended for anyone dealing with severe allergies or asthma.  It is designed to improve the air in the entire home through purification and the use of a HEPA filter.

The next biggest cause of allergy symptoms is changes in humidity levels.  Maintaining the ideal humidity level inside your home is often the next step that allergy and asthma suffers will take.  A whole-home dehumidifier/humidifier can be added to your HVAC system to help achieve that ideal humidity level.  The final, and most expensive, option is the addition of UV lamps.  A UV lamp can be used with your HVAC system to help you go beyond just trapping allergens to actually killing bacteria, mold and other allergy triggers.

One final recommendation is to stay on top of regular HVAC maintenance visits.  Having a technician thoroughly clean your HVAC system, as well as the ductwork, is the absolute best way to stay ahead of allergens.  It’s generally recommended to have this done annually, and spring is usually the ideal time.

3 Common Allergens to Worry About

Allergens

People worry about the outside air they breathe, but actually their main focus should be the air inside their home. With indoor air carrying 2 to 5 times more pollutants than outdoor air, poor indoor air quality is a concerning problem that should be addressed.

There are many allergens floating around both inside and outside, but some can be more troubling than others. Here are three of the most common allergens found in homes, and how to get rid of them:

  1. Dust Mites

Dust mites feed on human skin flakes and thrive in rooms with 40% humidity and above, and temperatures around 70 degrees. While they are commonly found in the bedroom, they can thrive anywhere in the house if it matches these conditions.

To eliminate as many dust mites as possible, wash all sheets, blankets, pillowcases, and bed covers in hot water. The water should be at least 130 degrees Fahrenheit to kill the dust mites. Use dust-proof covers on mattresses, box springs, and pillows to prevent their return.

  1. Mold

Mold loves wet, dark places in homes. The easiest way to keep mold spores from entering the air is to eliminate their chance of growing. Keep a fan on in the bathroom during and after showers, fix leaky appliances and faucets immediately, and use a dehumidifier when necessary.

If mold is found, call someone right away to get it looked at. Some mold can be toxic, causing even more serious health problems than an asthma attack or allergy flare-up.

  1. Pollen

While pollen has a huge impact outdoors, it can also have an impact indoors. Pollen can travel inside by clinging to clothing and shoes. Wiping down pets, keeping the windows closed, and using a media air cleaner can combat the issue of pollen inside the home.

Those with allergies or asthma shouldn’t have to suffer inside too. Take precautions to eliminate these three common indoor allergens and make breathing a little easier. Talk to Diamond Heating and Cooling about what they can do to help improve indoor air quality.
