MERV, or Minimum Efficiency Reporting Value, measures how well an air filter captures particles. Higher MERV ratings mean better filtration.

MERV 8: Captures pollen, dust mites, molds, and dust. Good for basic filtration needs.

MERV 11: Captures pollen, dust mites, molds, dust, auto exhaust particulates, pet dander, and allergens. Ideal for better air quality and allergy control.

MERV 13: Captures pollen, dust mites, molds, dust, auto exhaust particulates, pet dander, allergens, smoke, bacteria, and viruses. Best for superior air quality and advanced filtration.

Choose based on your specific needs for air quality and allergen control.

You should try to regularly maintain good air quality and keep your HVAC system running smoothly.

Typically, it's recommended to replace your air filter every 1 to 3 months, depending on factors like the type of filter you use, your home's air quality, and how often you use your heating or cooling system. If you have pets or allergies, you may need to change it more frequently. Regularly replacing your air filter helps ensure proper airflow, reduces strain on your system and improves energy efficiency.

Our filters are designed to be compatible with most standard HVAC systems. To ensure the perfect fit for your specific system, we recommend checking the size and type of filter required by your HVAC unit, which is usually indicated in the system's manual or on the side of your current filter.

If you’re unable to locate the correct size or if your system requires a custom filter, we offer custom filter options.

Yes, our filters can help with allergies and asthma by capturing airborne allergens. For enhanced relief:

MERV 11: Captures pollen, dust mites, mold spores, pet dander, and allergens. Ideal for general allergy control.

MERV 13: Offers higher filtration, capturing pollen, dust mites, mold spores, pet dander, allergens, smoke, bacteria, and viruses. Best for superior air quality and more comprehensive allergy and asthma relief.

We recommend the MERV 13 filter for the best overall performance and maximum protection.

Check your existing filter: If you have an old filter handy, take a look at the frame. You'll usually find the size printed there. Look for both the nominal size (often in larger letters) and the actual size (usually in smaller letters).

Measure the filter space: If you don't have an old filter or can't find the size information, simply grab a tape measure. Measure the length, width, and depth of the area where the filter will be installed.

It's time to replace your air filter if you notice any of the following: a burning smell (indicating overheating), declining air quality (more dust or allergies), difficulty maintaining a consistent temperature, or a sudden increase in your energy bills. These are all signs that your filter is clogged and preventing your HVAC system from operating efficiently.

Our filters are made from a combination of high-quality materials to ensure effective performance. They contain filter media, which is pleated to increase surface area for better filtration. The frame is crafted from 24-point beverage board, providing a sturdy structure, and the filter is reinforced with a wire mesh for added durability.

Yes, it is essential that you direct the air filter in the proper direction. The direction of the airflow is marked by an arrow on the main body of most filters. Installing it incorrectly could end up causing damage and reducing the efficiency of your HVAC system. To make sure that the filter has been set up properly for optimal performance, always follow the arrow.

Yes, you require an air filter that fits your system properly. A poorly fitted filter might let dust and particles pass through and may require more effort from your HVAC system. This can potentially harm your system and decrease efficiency. Choose an air filter that is exactly the right size for your system at all times for optimal performance.
