>Company Show
Thenow Purification Technology has focused on air filtration on HVAC industry for more than 16 years. We hope to bring the world more clean air with quality and environmental friendly filters.
>Certificates and Test reports
Standard is a ruler for the filters from all over the world. We have been trying to meet the most strict standard. Our HVAC air filters have been certified by CE, SGS and tested according to EN779, EN1822, Ashare and the latest ISO16890. You can rest assured when make a decision to buy.
>8+ years exporting experience
We have been to Powtech In Nurnberg in 2014, Achema in Frankfurt in 2015, AHR in Chicago in 2018, Chilliventa in Nurnberg in 2018. And our filters have been to all over the world: Europe, Middle East area, Africa, South Asian area, South American area and North American area.
>Professional Packing and Container Loading
Packing is important especially for carboard frame disposable filters and HEPA filters with glassfiber filter media. So we are very careful with it.
