3MH70-0712-6848-9 - 3M Adflo PAPR Pre-Filter (Pack of 6)

Keep Your Air Clean and Your Wallet Full

If you run a 3M Adflo PAPR system, you know that the fresh, cool air it provides is a game-changer for long days under the hood. But you also know that replacement High-Efficiency (HE) filters aren't exactly cheap. That's where the 3M Adflo Pre-Filter (15-0099-99X06) comes in. Think of this pre-filter as the bodyguard for your expensive main filter. It takes the hit so your HE filter doesn't have to. By catching the larger dust particles, grinding debris, and heavy soot before they can dig into the main filter media, these pre-filters can double or even triple the life of your primary filter.

Changing them out is incredibly simple and takes less than a minute. You just pop off the cover, slide this pre-filter in between the metal spark arrestor and the main purple HE filter, and you're good to go. There are no tools required, and it fits perfectly every time because it's a genuine 3M part. We know how dirty welding shops can get—flux dust, grinding sparks, and general shop grime are everywhere. If you don't use a pre-filter, all that junk goes straight into your HE filter, clogging it up and making your blower work harder. When the blower works harder, your battery dies faster, and you end up hearing that annoying low-flow alarm way too often.

This pack comes with 6 pre-filters, so you can toss a few in your gear bag or toolbox. A good rule of thumb for many full-time welders is to swap out the pre-filter once or twice a week, or whenever it starts looking dark and dirty. It’s a small price to pay to keep your machine running smoothly and to avoid burning through expensive consumables. Don't wait until your airflow drops to zero; keep a stack of these 15-0099-99X06 pre-filters on hand. Your lungs, your battery, and your bank account will thank you.

Whether you are using a Speedglas 9100 FX, a G5-01, or an older model with the Adflo unit, this is the correct pre-filter. It’s the smartest, cheapest insurance policy you can buy for your respiratory equipment. Keep the air flowing and the sparks flying with genuine 3M maintenance parts.
