Split A/C Unit users- read carefully

The split air conditioners without ducting with Hi wall fan units inside the room/hall are harmful to health if not properly installed. They are costly too and eat higher power than a window unit. There is no access to fresh air supply and thus Indoor air quality deteriorates with high bacteria, fibres, contaminants, body odors and CO2 accumulating over time. The raised Cor actually eats oxygen of room and replaces i thus persons may suffer eye burning, mental cell damage and raised level of CO2 in blood. Person feels tired.
Most of these units are just sold by ill trained dealers and service engineers are no proper installation advise and application advise is given. Customers should be careful in using these split A/c units and use proper drain water pipe and also fresh air fan to bring fresh air in room for replacement. In small bed rooms where only 2 persons sleep in night the air leakage from doores and window may or may not suffice. These are ideal for showrooms and busy shops only where door keep opening frequently and pushes air inside.

When I wrote, none of companies replied so far to my queries regarding this aspect despite several reminders including- Voltas, LG, ONIDA, Fedders Lloyd and carrier Aircon. It is clear case of suppressing vital information for greed to sell goods at the cost of consumer’s health and thus class action suit can be filed by NGOs/Consumers in group of 10 people.
In window air conditioners there is always a small opening to suck fresh air. And we have two setting exhaust and vent.
But in split fresh room has no communication at all with outside air with indoor fan unit.
The fibre filters put in a/c units (in fan side) actually may harbor more bacteria than they clean .As stated above these units can’t be fitted anywhere we like, as for window conditioners. Companies are not giving correct presale advise through their dealers and application engineers and hence are committing serious deficiency in service ,supplying of defective goods and goods harmful to public health. It is there duty to inform in a manual or catalogue as to where such units are suitable and how to install them.

Voltas and LG etc must reply to my questions. It is playing with lives of lacs of customers. Very serious matter

Please dont use split ductless unit in your homes/small offices where fresh air cant come in regularly. Demand compensation from AC suppliers and dealers for misrepresentation and suppression of vital information about consumer safety. It is covered under Consumer Protection Act 1986(COPRA)
Will these companies care to reply to these doubts? and take immediate corrective action.

More deatils for specific case can be asked from undersigned.

Enlightened members may comment please.After all it is public interest issue and we would like to rsolve the issue regarding usability and applicastion of ductles split A/C units being blidnly installed at various samll places not centrally airconditioned or through packeg conditoning system like 7.5 ton and above caacity.
