There is no cheap and easy way to solve the allergic reactions due to mold from the AC FCU.

Using air purifiers with replacement filters from TB + DIY aircon cleaning, preferably with a vario pressure pressure washer and 90 deg tip, or a 12V high pressure pump with 90 deg tip and solvent/detergent cleaners, once every 2-3 months, is already the cheapest method.

Either that or you operate 2 or even 3 air purifiers to get the necessary 8-10X ACH, Air changes per hour.

If you can DIY a fair bit, you can get by with a Xiaomi 2S operating at just 120 m3/hr airflow or something.
1-hr ug/m3 + PSI
