Ways to Prevent Allergens in Your Home


Many people suffer from allergies caused by dust, pollen, and ragweed – especially around springtime. Over-the-counter and prescription medications can be expensive and aren’t always enough to completely alleviate your symptoms.

What many people don’t understand is that if poor air filtration in your home exposes you to allergens, you’re probably suffering more than you have to. Investing in and maintaining a good filtration system for your home can vastly improve your home’s air quality and reduce your chances of being exposed to harmful allergens.

Types of Allergens

Home allergens are not all related to the springtime – dust, dust mites, and animal dander adversely affect people year-round. Children are especially affected by allergies, and can have respiratory issues related to airborne allergens within the home. Allergens originating within your own home permanently circulate through the air due to a poor filtration system, limiting your odds of ever living allergen-free.

Allergens can exist inside your carpets, air-conditioning vents, and upholstery – making them difficult to keep at bay. In new construction, materials such as sawdust and wood particles can linger in your home duct system and cause air pollution. Mold spores can gather within your walls from hidden plumbing leaks and spread throughout your home via your air conditioning.

What to Look for in a Filtration System

With a good filtration system, home allergens can be put to rest. A good filtration system protects your interior environment from harmful airborne allergens. Such systems usually have:

  • HEPA (high-efficiency particulate air) filters, which remove 99.97% of particles from the air
  • Permanent or disposable air filters with high MERV (minimum efficiency reporting value) ratings
  • A balanced filter triangle – capacity, airflow, and efficiency
  • A fully sealed HVAC system that does not allow in unfiltered air

With these main qualities, you can be sure that your filtration system is top-notch and won’t allow any unwanted allergens to come into your home or continue to circulate through your interior filters.

Other Ways to Protect Your Home

Besides updates and maintenance to your filtration system, you can focus on keeping your home humidity level below 50% to discourage the formation of mold, vacuum with a HEPA filter to eliminate pet dander and dust, and keep windows and doors closed to prevent pollen from coming inside.
