Intake (Pre-filters):

👉 Every 1–3 months depending on dust levels and airflow requirements.

These filters protect the booth from incoming contaminants.

Exhaust Filters (Paint arrestors):

👉 Every 100–150 spray jobs or sooner, especially if there's a drop in airflow or visible overspray buildup.
These are critical for capturing overspray and protecting the environment.

Ceiling Filters (if applicable):

👉 Every 6–12 months or when pressure drop is too high.

MERV stands for Minimum Efficiency Reporting Value. It's a standard rating system developed by ASHRAE (the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) to measure how effectively an air filter captures particles of different sizes.

MERV ratings range from 1 to 20.

The higher the MERV rating, the more particles the filter can trap — including dust, pollen, mold, bacteria, and even smoke or viruses at the top levels.

Depending on the amount of traffic your home or business receives can help determine how often your air/furnace filters need to be replaced. Regular filter changes can help reduce pollutants in the air and lower energy bills (as estimated by a 1-inch standard pleated filter).

• Lower traffic homes/apartments (single occupant/no pets): every 3-4 months
• Moderate traffic homes (no pets): every 90 days
• Moderate traffic homes with pets: every 60 days
• Densely populated households with more than 2 pets/occupants with allergies: once every 30 days
