Dust Collector Filters: What You Really Need (and Why HEPA Isn’t One of Them)

When it comes to keeping your salon safe, clean, and comfortable, dust control is one of the most important things to get right. Filing, e-filing, and enhancements all create fine dust that can build up on your surfaces, in your lungs, and even in the air clients breathe. That’s why nail techs often ask: “What filter do I need in my dust collector? Do I need HEPA?”

Let’s clear up the confusion once and for all.

Do You Need a HEPA Filter?

The short answer: No, you don’t.

HEPA filters are designed to capture microscopic particles such as pollen, smoke, and bacteria floating around in the air. They’re brilliant for air purifiers in your home and in large areas such as offices and hospitals, but they’re not designed for the type of dust created when you file nails.

Here’s why:

• Dust collectors capture at the source. They’re built to pull dust down as you file, before it can spread into the room. Because the particles are larger and heavier than airborne allergens, a high-quality fine dust filter is more than enough.
• HEPA filters clog quickly. The heavier nail dust particles can block a HEPA filter in no time, reducing suction and making your dust collector less effective.
• You’ll spend more replacing them. HEPA filters are costly and need frequent changing when used for nail dust - money that’s better invested in the right collector filters.

What filter do you need

Instead of HEPA, dust collectors need a multi-layer fine dust filter. These are designed to:

• Catch large and fine nail dust particles efficiently
• Maintain suction power without clogging too quickly
• Be cleaned or replaced easily to keep your machine running smoothly

Dust Collector vs. Air Purifier: Know the Difference

This is where a lot of nail techs and industry marketing get confused. Let’s break it down:

Dust Collector

• Captures dust at the source (right as you’re filing)
• Uses strong suction and fine dust filters
• Protects both you and your client from breathing in nail dust

Air Purifier

• Cleans the air in the room
• Uses HEPA and sometimes activated carbon filters
• May include antimicrobial or antibacterial features to neutralise airborne bacteria and viruses

Do You Need Antimicrobial Filters?

Some people assume that because air purifiers have antimicrobial features, dust collectors should too. The reality is: you don’t need this in a dust collector.

Why?

• Nail dust isn’t the same as airborne germs.
• Your client will still be in front of you, able to spread any airborne germs.
• The most important thing is capturing dust efficiently at the table.
• Proper salon hygiene (disinfecting tools, cleaning surfaces, washing hands) already handles the microbial side of things.

If you want clean, dust-free air while working:

• Choose a dust collector with fine dust filters (not HEPA).
• Add an air purifier with HEPA/antimicrobial features to the room if you want extra protection against allergens or germs.

By knowing the difference, you’ll save yourself money, confusion, and keep your salon healthier without overcomplicating things.

Think of your dust collector as your dust bouncer - it catches trouble at the door. Your air purifier is more like a room freshener - it keeps the whole place comfortable. Both have their role, but they’re not the same!
