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!
