Frequently asked questions about Filti

Why is it important to change air filters on-time every time?

Regularly changing air filters is crucial because they trap dust, allergens, and pollutants, ensuring clean air circulation in your HVAC system. Neglecting filter changes can lead to reduced air quality, decreased system efficiency, higher energy bills, and potential strain on the equipment.

What is MERV? Which filtration level is best for me?

MERV stands for Minimum Efficiency Reporting Value, which rates the effectiveness of air filters. The scale ranges from 1 to 20, with higher numbers indicating better filtration. The best filtration level depends on factors like allergies, pets, and indoor air quality goals. For most households, a filter with a MERV of 8 to 12 strikes a balance between efficient filtration and airflow.

How do I know my air filter sizes?

To find your air filter size, check the current filter or the filter slot for dimensions printed on the frame. Measurements typically follow the format: width x height x depth (e.g., 16 x 20 x 1). If you can’t find the information, use a measuring tape to accurately measure the filter slot’s dimensions.

The difference a filter can make.

When you switch to Filti, you’re making the choice to breathe better air everyday. Filti home air filters protect you from polutants around your home, dust and dirt in your HVAC system, and even seasonal allergens. Keeping your in-home air quality protected with Filti is a no-brainer.
