IQ AIR;

Thanks for the info. The IQ air assessors are coming next week to check out the flat and give a report on the suitability of installing a purifier. They have asked that on the day of the check ensure all doors and windows are closed from early morning and the air conditioners are off. However if it's a hot day the air conditioners may be switched on. This seems a bit contradictory but no doubt the test makes some allowance for whatever, or does it!! I may be interested in your 150s. Regards,
