The Airteva filter frame

You will get the Airteva air filter frame, uniquely designed and patented. This durable frame is made entirely of aluminum and includes a special Leak-Guard Seal to prevent air bypass.

It also has a built-in electrostatic screen to boost its performance. We will custom-make your new frame in any size you require, ensuring a perfect fit for your filter every time.

customized leak guard seal

AIRTEVA Filters are designed with a patented Leak-Guard Seal to guarantee that air and pollutants pass through the filter, not around it. When your air conditioner or furnace is on, the pressure change creates an airtight seal. This means no air bypasses the filter, ensuring all the air is effectively filtered.

Best Filters

 "Could not live or breathe without these filters. Very seldom use my inhaler at home because of them. You can see the results when you change the filter, so you know it is doing what they say it will do. I have tried HEPA filters, charcoal filters, and certain other filters that gave me asthma attacks from the materials they were made from. These are absolutely perfect."

How custom air filters are made


Q: Why would I need a custom sized air filter?

A: You might need a custom size filter if standard sizes don't fit your HVAC system, or if you have specific air quality needs that standard filters can't meet. Custom filters ensure a perfect fit and optimal air quality.

Q: How do I order a custom size air filter? 

A: To order a custom filter, you typically need to know the exact dimensions you require. You can usually order online by entering your specific measurements and choosing your desired filter type. 

Q: Can custom air filters address specific air quality issues? 

A: Yes, custom air filters can be designed to address various air quality issues, including allergies, pet dander, smoke, and more. You can choose filters with specific features, like activated carbon or HEPA filtration, to tackle your particular concerns. 

Q: How often should I replace my  air filter? 

A: The replacement schedule can vary based on the type of filter, your air quality, and how much your HVAC system is used. Generally, it's recommended to check filters every 30 days and replace them as needed, usually every 2-3 months. 

Q: Are custom filters more expensive than standard filters? 

A: Custom air filters can be more expensive due to their tailored design and the specific materials that might be required. However, investing in a custom filter can improve your HVAC system's efficiency and the air quality in your space. 

Q: How do I measure my HVAC system for a customized air filter? 

A: Measure the length, width, and depth of the current filter slot or the existing filter if you have one. It's important to measure accurately to ensure the filter fits perfectly. 

Q: Can I return a custom sized filter if I order the wrong size?  

 A: Return policies vary by manufacturer. Due to their custom nature, some companies may not accept returns on custom filters, so it's crucial to double-check your measurements before ordering.
