Great filter that beat the competition hands down.

Have used these filters for three years. Have also purchased look a like's that I returned. Will never use the competitors again. Learned my lesson.

Which humidifier models are compatible with Filter T?

The HFT600 (Filter T) is specifically designed for the Honeywell Top Fill Tower Humidifier series. It is compatible with:

HEV615 Series: HEV615, HEV615B, HEV615W.
HEV620 Series: HEV620, HEV620B, HEV620W.

What is the benefit of the blue pre-filter layer?

This filter features a multi-stage design that includes a blue pre-filter layer. This outer layer captures large airborne particles such as dust, lint, and pet fur before the air passes through the main wicking filter. It also provides extra structural support to help the filter maintain its shape when wet.

Does this filter help with "white dust"?

Yes. These are evaporative wicking filters. They are designed to "trap" minerals and pollutants from your water within the filter material. This prevents those minerals from being released into the air, which is what typically causes the messy white dust associated with ultrasonic humidifiers.

How does the antimicrobial treatment work?

The HFT600 is Protec antimicrobially treated, which helps inhibit up to 99.99% of mold growth and the migration of algae and odor-causing bacteria on the filter surface. This ensures that the moisture being added to your home remains clean and fresh.

Ensure your home stays comfortable throughout the dry season with the Honeywell HFT600 Filter T 2-Pack. Designed specifically for the Honeywell HEV615 and HEV620 Removable Top Fill Cool Mist Humidifiers, these genuine filters are your best defense against mineral buildup and airborne impurities.

By choosing the 2-pack, you’re always prepared for your next filter change. We recommend replacing your filter every 30-60 days to maintain the cleanest moisture output possible. These filters aren't just compatible - they are the original manufacturer equipment (OEM) required to protect your humidifier's motor and ensure the longevity of your device. Don't settle for generic "comparable" brands; stick with Genuine Honeywell Filters for guaranteed fit and performance.

Each Honeywell HFT600 Filter T in this 2-pack is engineered with a multi-stage filtration system to improve your indoor air quality and protect your humidifier. The integrated blue pre-filter layer acts as a first line of defense, capturing large airborne particles, while the high-efficiency wicking filter traps minerals to prevent the "white dust" often associated with hard water. To ensure the moisture entering your home remains clean, these filters are Protec antimicrobial treated, which inhibits the growth of mold, algae, and odor-causing bacteria directly on the filter surface.
