Hi. Thanks for responding.

• i don't think you're aware that FDA was ordered by court to withdraw it's slanderous and suggestive horse-paste advertisements? Court case info is included in this article. In the court case info you can read where FDA acted unlawfully. Regarding "denialism and intentional misinformation" i tried finding this court-case in the mainstream, but mainstream news is silent about this ruling against FDA.

Indeed.. and Dutch government acted like it was interested by funding 2 studies of Dutch airfiltering products. But halted studies halfway for nothing..
One company installed the air filtration systems in primary schools for free. Guess what.. indeed, schools were very positive. Govt couldnt care less!
