The majority of people do not know that indoor air pollution can often have much higher levels than outside. This is not good for people who suffer from allergies or asthma as these pollutants are the direct cause.
Indoor Air Pollutants
Your home could be harboring any number of common indoor allergens such as:
- Pet dander (skin flakes), saliva, and urine
- Dust mites
- Cockroach droppings
Once airborne, these particles enter your body through breath and cause a reaction internally, which results in sneezing, coughing, runny nose, or worse symptoms.
How Your Home Harbors Pollutants
The heating, ventilation, and air conditioning (HVAC) system in your home can both harbor and spread mold and other allergens. Old HVAC units circulate indoor air. With the old units, you can be breathing in the same mold over and over again while your body continues to react to it. The modern day solution is to purchase HVAC systems that bring outside air in that is constantly filtered.
Always Use Fresh HVAC Filters
There are multiple different types of filters you should be aware of when replacing your old used ones.
- Flat panel filters- Are designed to protect the furnace, not improve indoor air quality.
- Medium efficiency filters. -Have a higher surface area so they filter more particles out of the air.
- High efficiency filters.-Remove even smaller particles than pleated filters.
- HEPA filters. High-efficiency particulate air (HEPA) filters use high energy
Since higher efficiency and HEPA filters tend to put so much stress on your HVAC system, you may want to use a medium efficiency filters since they still work really well and they are cheaper.
The best HVAC experts can help you pick out which filter fits your needs and install it for you any time.
