Dri-Eaz^® dehumidifiers now come with the new 4-PRO™ filter designed specifically for restoration, remediation and construction jobs.

As the replacement for the discontinued 3M HAF filter, the 4-PRO filter captures dust and debris to protect internal components, and even helps to control odors.

The 4-PRO works in four ways to preserve dehumidifiers’ efficiency while protecting operators and occupants:

• Expanded cellulose mesh reduces build-up on internal dehumidifier components by capturing large particles
• Electrostatically charged polypropylene captures smaller particles
• Activated carbon adsorbs odors and fumes
• Antimicrobial-treated layers help to prevent bacterial growth on the filter.

The 4-PRO’s rigid aluminum frame protects against filter collapse and ensures proper filtration throughout the filter loading cycle. “If paper filter frames get damp, they can bend or crumple up and leave the dehu unprotected,” said Dan Gibart, Restoration Equipment Category Manager. “The 4-PRO filter’s aluminum frame prevents this from happening.”

Introduced with the LGR 6000Li in 2018, the 4-PRO filter now ships with the LGR 7000XLi, Revolution LGR, and DrizAir 1200 refrigerant dehumidifiers, plus the DriTec 4000i desiccant.

The 4-PRO is not reusable and should be discarded after use. Legend Brands recommends replacing the filter whenever the accumulation of dust and debris is visible or after every job where there is a risk of cross-contamination.

Replacement 4-PRO filters can be purchased from authorized distributors for the Dri-Eaz dehumidifiers listed above plus the Evolution LGR. 3M HAF filters are currently being sold for other models – the LGR 2800i, 3500i, 2000 and 2400 – until mid-Spring when the 4-PRO filter will be available for these remaining models.
