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. Additionally, these devices provide numerous other benefits such as improving indoor air quality so overall they are an ideal solution for reducing people's exposure to hazardous pollutants while providing necessary relief from uncomfortable illness caused by allergies.

It may seem ironic that the very tool used to clean up air indoors could itself require some cleaning. But home air filters, which are installed in HVAC systems and ducts to remove pollutants from indoor air, do indeed need regular care and maintenance in order to function optimally. So the question is: can a homeowner clean their existing filter instead of buying a new one?


The answer depends on several factors. The type, size and condition of the filter will determine whether or not it is suitable for cleaning. For example, disposable fiberglass filters must be completely replaced after they've been used for three months because they become clogged with dirt and dust particles over time. On the other hand, permanent electrostatic filters can often be cleaned with detergent or vacuumed regularly - though usually only if they're in good condition (i.e., free from mold growth).


Ultimately, homeowners should check with their HVAC system manufacturer before attempting to clean any kind of air filter themselves as different systems have different requirements. With proper care and maintenance, however, an existing home air filter can provide effective relief from allergies for many years without needing to buy a replacement every few months.

A home air filter can be a great asset when it comes to ensuring the cleanliness of indoor air. However, many people are concerned about how noisy these filters might be. To address this query, it is important to understand the mechanics behind these devices and whether they cause any bothersome noises or not.


The main source of noise from an air filter is typically related to its operating speed. Most residential models operate at low speeds, which means that their fans generate minimal amounts of sound. Some higher-end versions may have rotating blades that move faster for more efficient filtration but will also produce louder sounds in comparison. The amount of noise generated by each model will vary depending on its size, quality and type of fan used, as well as other factors such as insulation and ventilation system within the building itself.


Overall, while some models may create a slight humming sound, most modern home air filters are designed with noise control features like insulated housings and quiet operation modes to limit disruption. Thus, homeowners should feel confident in knowing that their purchase won't keep them up all night long.

The use of home air filters has become increasingly common in recent years. A primary benefit of these devices is the removal of pollutants, allergens and other airborne particles that can be hazardous to a person's health. However, there are also potential risks associated with the use of such filters which should not be overlooked.


The first potential risk involves incorrect installation or maintenance of the filter itself. If the device is improperly installed then it may not work correctly and could even cause further contamination within your home environment. Additionally, if regular cleaning isn’t performed on the filter then this too can lead to additional problems as dirt and dust will accumulate over time.


Finally, some research suggests that certain chemicals used in air filtering devices may actually have adverse effects when breathed in by humans over long periods of time. Chemicals like ozone and formaldehyde have been linked to respiratory issues for those exposed at high levels. 


Here are a few tips to reduce potential health risks from home air filters:


  • Regularly changing out or replacing the filter

  • Ensuring proper ventilation around the filter system

  • Avoiding models containing potentially harmful chemicals
