Frequently Asked Question

Achieving optimal air quality inside the home is of upmost importance, particularly for individuals with allergies or respiratory issues. To ensure that an environment remains conducive to health and wellbeing, it is necessary to consider how often home air filters should be changed.


Regular maintenance of the filtration system can have a significant impact on overall indoor air quality. Generally speaking, changing out the filter every 30-90 days is recommended in order to provide effective protection from airborne particles:

• Dust

• Pollen

• Pet Dander

• Mold Spores


Failing to adhere to this schedule can limit the effectiveness of your filtering system and may lead to inadequate removal of pollutants from circulating air. Furthermore, clogged filters reduce airflow which can cause strain on HVAC systems and result in higher energy bills. Therefore, regular inspection and changes are essential for maintaining good indoor environmental quality as well as efficient operation of the heating/cooling unit.


Proper upkeep of home air filters should not be overlooked if one wishes to preserve beneficial air quality and cost efficiency within their residence. Frequency of replacement will depend upon individual circumstances but periodic checks are highly encouraged in order to maximize performance and protect against potential hazards.

When considering the effectiveness of home air filters in controlling allergies, one might initially question how much relief they can offer. However, there is scientific evidence that supports their ability to reduce allergen levels and alleviate allergy symptoms.


Firstly, many studies have shown that properly installed and maintained filters can capture as much as 90% of airborne particles measuring 1 micron or more in diameter - this includes dust mites, pet dander and pollen. Secondly, research indicates that using a high-efficiency particulate air (HEPA) filter for example helps trap 99.7% of even smaller particles such as bacteria and tobacco smoke. Thirdly, tests have been conducted which demonstrate that placing filters near heating vents where allergens often accumulate has resulted in significant decreases in particle concentrations. Finally, HEPA filters also help improve indoor air quality by decreasing humidity related mold spores from entering living spaces.


It is evident that using home air filters offers effective protection against various types of allergens which cause allergic reactions when inhaled or ingested into the body.
