FLEXIT S4R/S6R/S7R 2xF7+2xG4 Filter set (Older variant sale!)

We are keen to supply you with top-quality air filters for the perfect indoor climate at the best price. We offer more than just a filter:

• Experience and professional support: our consultants have long-term experience in HVAC production and service fields.
• Wide range:  multiple options, including activated carbon, and energy-efficient filters for the most AHUs.
• Fast delivery: over 40000 filters in our production warehouse are ready to be shipped next/same working day.
• Quality materials:  filtering materials are made by leading companies such as SANDLER AG and have high efficiency and dust-holding capacity.
• Top quality: all the filters, including of G4 class are glued to the frame to ensure maximum airtightness. 
• Low prices: due to the short supply chain and high volumes we offer probably the best prices for quality filters in the EU.
• Made in the EU. Over 85% percent of the ventilation filters sold in the EU are made in China from low-quality materials. 
• Tested efficiency. Filters are tested in an accredited laboratory in Germany according to ISO16890 standards 

Filter is a replaceable component of any ventilation equipment therefore sustainable production and logistics play a key role.

Production:

• High-quality 3-ply filtering material has a larger dust-holding capacity. Therefore, filters serve longer, and less material can be used in production.
• We do not use glass fiber material in filters. Glass fiber is fragile, potentially hazardous, and non-recyclable.
• Panel filter frames are made of moisture-resistant cardboard. The supplier uses the maximum possible amount of recycled cardboard production.
• Energy in production plants comes from renewable sources.
• Filter frames for certain Zehnder ComfoAir models are made of eco plastic with organic materials content of more than 80%.
• Offer filter options made of energy-efficient materials, with 1.3-2 times longer replacement periods.
• Due to patented technology, we use 30-50% less glue than used in other alternative filters.

Shorter delivery distance:

• Materials for production are made by factories located in the EU countries.
• Filers made in the EU (more than 80% of filters in the market are made in China or other Asian countries).
• We deliver directly from the production warehouse.

We are constantly searching the ways to provide more sustainability to your filter!

PFAS chemicals have been used in a wide range of products since the 1940s. PFAS can migrate into soil, water and air during production or use. Most of these chemicals are practically non-degradable. A number of scientific studies indicate that PFAS chemicals may pose a risk to human and animal health.
