AC Filter Replacement


Indoor air quality plays a vital role in our overall well-being. One of the key factors in maintaining clean and healthy air is regularly replacing your AC filter. 

We will explore the importance of AC filter replacement. There are different types of filters, and selecting the right size and type of filter is essential. Doing so can improve indoor air quality, the HVAC system's efficiency and reduce energy bills.

Why Replace Your Air Filter?

A dirty air filter can adversely affect your health and your HVAC system's performance. Over time, airborne particles like dust, pollen, pet dander, and mold spores accumulate in the filter. This obstructs the airflow and reduces the system's efficiency.

Not changing air filters can have negative consequences. These include poor indoor air quality, increased energy consumption, higher energy bills, and potential damage to your HVAC unit.

Types of AC Air Filters

Regarding HVAC filters, pleated filters are popular when purchasing air filters through big box stores such as Home Depot or Lowes. Home Depot air filters tend to cost more for lower quality and are sold in packs of two. Filters Direct USA ac filter replacements include antimicrobial materials and a tacky surface to better trap dust, dander, and allergens.

Antimicrobial ac filter replacements are particularly beneficial for individuals with allergies or respiratory conditions. They can significantly reduce airborne irritants and improve the overall air quality in your home.

Selecting the Right Size Filter

To ensure optimal filtration and airflow, choosing the correct size filter for your HVAC unit is crucial. In older homes, air filter replacements are less standard than in new home builds. The standard air filter sizes of 20x20, 16x20, and 16x24 are usually missing on the shelf in Home Depot or Lowes.

Using the wrong size can lead to air leakage around the filter. This means air is bypassing the filtration system altogether. You can grab a yardstick or measuring tape to identify the height and width of your air conditioner filters. Most air filters are one inch in depth. 

At Filters Direct USA, each filter is cut custom to your home's filter size needs. Proper sizing will ensure that your filter fits snugly and effectively captures contaminants, improving the indoor air quality in your home.

Regular Replacement for Maximum Efficiency

Replacing your air filter regularly is key to maintaining a healthy and efficient HVAC system. The general guideline is to replace the filter every 90 days. This can vary depending on the number of people in the home and how many furry pets live there.

Additionally, consider checking the filter's Minimum Efficiency Reporting Value (MERV) rating. Higher MERV ratings indicate better filtration efficiency, but they may also restrict airflow if incompatible with your HVAC system.

Strike a balance by choosing a filter with an appropriate MERV rating that suits your needs. The higher the MERV rating does not mean it is "better." Your home's heating, ventilation, and air conditioning rely on airflow.

Filters Direct USA offers MERV 9 filters. They combine antimicrobial material and a tacky layer to trap dust mites, human skin, dander, dust, pollen, and hair particles. MERV 9 was specifically selected to allow airflow to move through the system properly. If the unit is working too hard to pull air through the high MERV rating filter, your energy bill will increase, and the life of your HVAC unit will decrease.

Reduce Strain on the HVAC Unit

By replacing your AC filter as recommended, you'll improve your indoor air quality and enjoy several additional benefits. A clean filter ensures proper airflow, reducing strain on your HVAC unit and extending its lifespan.

An efficiently operating HVAC system can lower energy consumption and decrease energy bills. Regular maintenance, including filter replacement, is a small investment that can save you money in the long run.

Benefits of Regular AC Filter Replacement
  1. Extended AC Lifespan. When the air filter is clogged, it strains the AC system's components, such as the fan motor and compressor. This can increase wear and tear, potentially shortening the unit's lifespan. When air filters are replaced on schedule, you can reduce the risk of unnecessary damage to the AC system. This will help it last longer.
  2. Cost Savings. An AC system with clean air filters operates more efficiently, lowering energy bills. Extending the lifespan of an AC unit is possible with regular filter changes. This can help save on the expense of premature replacement or costly repairs.
  3. Consistent Cooling Performance. Clogged air filters can restrict the airflow and cause uneven cooling throughout your home or office. Regularly replacing filters ensures consistent airflow and maintains a comfortable indoor environment with even cooling distribution.
  4. Preventive Maintenance. Regularly replacing air filters is a simple and inexpensive ($12 per filter through Filters Direct USA) form of preventive maintenance. It helps prevent more significant issues, such as frozen coils, overheating, or a complete system breakdown. By staying on top of filter replacements, you can minimize the risk of major AC problems and associated costs.

Summary

Do not ignore the effect of a properly maintained air conditioner filter. It can improve indoor air quality and your HVAC system and lower energy bills. Filters Direct USA filters can help you achieve a cleaner living environment.

Select the right size for your needs and regularly invest in ac filter replacements. This can improve air quality, better health, and potential cost savings.
