Harvia WHM25 Sauna Chimney Vapor Barrier

The Harvia WHM25 is a red vapor barrier for Harvia steel sauna chimneys. It goes at the sauna ceiling, around the chimney where it passes through, and it helps with moisture control and energy efficiency by preventing moisture from penetrating the sauna wall and ceiling and reducing heat loss. It measures 21.65 x 21.65 in (550 x 550 mm) and weighs 1.1 lbs (0.5 kg). It is for interior wet-area use. The chimney, stove and other parts are sold separately.

Where it fits in the chimney system

Dealers say the WHM25 is made for the Harvia WHP1500 and WHP1500M steel chimneys, and that it is not included with the chimney kit, so you order it separately. It is installed at the sauna ceiling, around the chimney.

Check the fit before you order

Harvia lists the part as a vapour barrier for a 225-250 mm chimney, while dealers describe the opening as about 8.1 in (205 mm), so the sources do not agree on the opening size. Please contact us to confirm that the WHM25 fits your chimney before you order. Follow the chimney's installation manual and your local building and fire codes.

Superior Customer Service

Mediriser was excellent to work with to get a custom-sized hospital mattress and bed. William kept me informed throughout the process. I will contact them directly for any of my future DME needs.

IBIS Wheelchair to Car Lift

The IBIS wheelchair to car lift was a game changer for us. My husband has been in a wheelchair for more than 40 years and we have never seen anything like this in the US and had no idea such a lift exist existed.

My guy is hemiplegic and usually able to stand pivot into the car but he broke his femur in November 2025 and had to be non-weight bearing for 3 months. He lost so much strength and ability that he could no longer do any kind of safe transfer.

Our friend found the IBIS wheelchair to car lift online and we decided to take the risk. It was worth every penny and more. Within a day of its arrival we were mobile and in and out of the car again. It is very manageable for me to operate and in our 60’s we are grateful for anything that lightens our load.

Everything arrived as advertised. Customer service was outstanding with clear communication. I was provided help to ensure my measurements were correct and was offered a few options to customize the sling. We had to get a new car right after we bought the lift and it was a good fit in the new car.

We are very pleased and highly recommend this product.

It works very well

Annetta Voigt

I love the fact it installs along the side and does not have a huge footprint. It works great lifting scooter or wheel chair. Easy to use.

Fantastic Experience from Mediriser

Fantastic experience with Mediriser! We purchased a red light therapy bed and an HBOT machine. The customer service team was incredibly responsive throughout the entire process. Even when we hit a few unexpected bumps, they completely took ownership and went above and beyond to resolve them. Highly recommended for wellness equipment!
