1. Measure the dimensions of your existing air filter
To ensure that your custom air filter will fit properly, you'll need to measure the dimensions of your current filter. This includes the length, width, and depth of the filter. Make sure to measure in inches as precisely as possible.
2. Choose the filter media
Custom air filters can be made with different types of filter media. Standard options include fiberglass, polyester, and pleated. Look at what your current filters have listed on the side. Consider the specific needs of your home and your HVAC system when choosing a filter media. For example, if you have pets, choose a filter media with a higher MERV rating to capture pet dander. We can help you determine if you are not sure.
3. Send us a message or call us
Provide us with your measurements, filter media choice, and other relevant information. Make sure to double-check your order before submitting it to ensure that all the details are correct. Call or text us at 954-588-7774. You can also drop us a note in the below form.

A/C Filters 4 Less is one of the best companies I have ever dealt with. Their prices and knowledge are the very best. I can't say enough about how great their customer service is, which we all know is very rare these days. I ordered the wrong filters by mistake and Mark went out of his way to help me - he was more than fair! I plan on ordering all my filters from them in the future. I would give them 10 stars if I could!

Ensuring an Accurate Fit:
Provide the Right Information to Your
Custom Air Filter Supplier
It's essential to recognize that the stamped size on most air filters does not necessarily reflect the actual dimensions of the filter. For instance, a filter labeled 20x20x1 may measure 19 3/4 x 19 3/4 x 3/4. We encourage you to measure your current air filter carefully to ensure you get the precise dimensions. By providing the exact measurements, we can create a custom filter that fits like a glove.
Unmatched Quality and MERV Ratings:
Choosing The Right Custom Air Filters for Cleaner and Healthier Indoor Air

At AC Filters 4 Less, we take pride in offering custom air filters crafted from high-quality materials that deliver exceptional performance. With a comprehensive range of MERV ratings available, from MERV 8 to MERV 13, you can select the perfect filter that matches your needs. Enjoy peace of mind knowing that our filters effectively capture airborne contaminants, ensuring cleaner and healthier indoor air.

Customer Filters are available in following filters type.

Fiberglass MERV 3-4
A MERV rating of 3-4 is typically considered suitable for capturing larger particles such as pollen, dust mites, and carpet fibers—filters with this rating suit residential settings with minimal air quality concerns.
Polyester MERV 5-6
A MERV rating of 5-6 is considered good for capturing smaller particles such as mold spores, pet dander, and fine dust. They are commonly used in homes, offices, and commercial spaces where moderate air quality concerns exist.
Pleated MERV 8
Good for capturing a wide range of particles, including dust, pollen, mold spores, pet dander, and other common household allergens. Strikes a balance between filtration efficiency and airflow, providing effective particle capture while allowing adequate airflow for HVAC systems to operate efficiently.
Orange & White Media Pads
The perfect AC filter solution since they trap more dust without reducing the MERV rating, unlike pleated filters. These are best for people with allergy concerns. They hold the most dust and debris without restricting the airflow like a pleated filter can.
Pleated MERV 10
Provides a higher filtration efficiency so commonly used in residential and commercial settings, including offices, schools, hospitals, and other spaces where higher air quality standards are desired. Ensuring that your HVAC system can accommodate airflow resistance is essential. 

Pleated MERV 13
Used in environments where the highest level of filtration is expected, such as hospitals, laboratories, and other sensitive spaces. It may have higher airflow resistance, so it's essential to ensure that your HVAC system can handle the increased pressure drop.


The Benefits of Using Custom
Filters for HVAC Systems

Custom air conditioning and furnace filters are an excellent option for homeowners and businesses looking for a more precise fit for their HVAC systems. These filters are made to order, with the dimensions and specifications tailored to match the specific needs of your equipment.

Another benefit of custom-sized filters is that they can be made to match the particular needs of your HVAC system. For example, you can choose unique size air filter media with a higher MERV (minimum efficiency reporting value) rating to capture smaller particles, such as pet dander and mold spores. You can also choose filter media made of different materials, such as synthetic or natural fibers, to suit your needs. Custom-size filters are also great for hard-to-fit HVAC systems, such as those in older homes or commercial buildings. These filters can be made to fit unique dimensions, ensuring your system runs at its best.

It's important to remember that custom HVAC filters are more expensive than standard off-the-shelf filters, but they can be worth the investment for a better fit and improved performance. Plus, we guarantee the lowest prices on the internet for special-size air filters.

Custom air filters vs. custom furnace filters:
Understanding the difference.

It's critical to recognize that custom furnace filters and custom A/C filters are essentially the same. The terminology used may vary depending on the region or individual preference. People in the North, for instance, frequently call them "furnace filters," while those in the South frequently call them "AC filters." Whatever you call them, providing specialized filtration solutions for HVAC systems remains the goal and function. You may be sure that the answer meant to improve indoor air quality and safeguard your system is the same whether you need a custom furnace filter or an AC filter.
