Typical kinds include:

HEPA filters.
UV light filters.
Electrostatic filters.
Washable filters.
Media filters.
Fiber glass filters.
Pleated filters.

MERV vs HEPA Filters – Key Differences Explained

In any commercial HVAC filter buying guide, deciding between MERV vs HEPA filters is one of the most frequent choices. Although they have different uses, both are very efficient solutions.

What Are MERV-Rated Filters?

The MERV rating, short for Minimum Efficiency Reporting Value, shows how well a filter catches particles between 0.3 and 10 microns. The higher the MERV rating (1-16), the better the filter traps tiny particles.

MERV 1–4: These filters handle bigger things like pollen, textile fibers, and dust mites, too.
MERV 5–8: Steps it up. It grabs regular household dust, pet dander, and mold spores.
MERV 9–12: ideal for household or commercial use, they capture fine particles such as lead dust and car exhaust particles.
MERV 13–16: achieve near-hospital-grade filtration by capturing bacteria, the majority of smoke, and other small particles.

What Are HEPA Filters?

HEPA stand for High-Efficiency Particulate Air, and it’s a tougher standard than most. True HEPA filters, as evaluated outside of the MERV scale, must eliminate at least:

99.97% of particles (U.S. standard) are over 0.3 microns.
The ISO/European norm is 99.95% of the same.

Because of this, HEPA filters are the preferred choice for settings such as cleanrooms and hospitals that require very clean air.

Pleated Filters – A Cost-Effective Industrial HVAC Solution

Pleated filters are popular in commercial and industrial systems because they strike a balance between cost and effectiveness.

What Are Pleated HVAC Filters?

HVAC pleated filters are used in HVAC systems to protect your equipment and reduce airborne pollutants. Pleated filters save energy due to their high dust-holding capacity and low pressure drops.

The pleated cloth or paper used to make pleated filters is folded into a series of tiny pleats, increasing the filter’s surface area and the number of particles it can capture.

Air purifiers, air conditioners, and other indoor air quality equipment often use this type of filter. Numerous trustworthy pleated filters manufacturers create custom industrial HVAC filter solutions to meet specific facility requirements.

When to Choose Pleated Filters Over HEPA or MERV

Pleated filters are a useful compromise in the debate between MERV vs HEPA filters.

Select pleated filters in the following situations:

There are financial limitations.
Filtration at the HEPA level is not required.
Saving energy is a top concern.
