First, I'm assuming you mean "Flying."
The types are Electric, Rock, and Ice.
I think AIR is the most effective mean of corrosion and the most appealing example is the corrosion of iron when it comes in contact with air.
In hot climates.
Air supremacy is the most most favourable state of control of the air in a war, where the opposing air force is incapable of effective interference.
A heat-pump is the most cost effective air conditioning system. It will maintain the temperature in your home while expending the least amount of energy.
No, the m50 mask is not the most effective in confined spaces where there is not enough oxygen in the air to breathe to support life.
The filters that are the most effective if there are pets in the house would be either an ionizing air filter or a HEPA filter , both which help eliminate the animal dander in the air .
Use of air planes allows the military to place bombs where they will be most effective.
There are a number of personal air purifiers that are deemed to be highly effective. Sharper Image and Kenmore, for example, both make air purifiers that are highly rated.
Seat belts & air bags.
If you're talking types, and mean flying-type instead of air, and by opposite you mean what is super effective against flying-type, then the answer is electric, rock, and ice.
there are a lot of ways, but the most effective way is blazing (air and fire) and water
The most effective ways to filter air conditioning systems for optimal performance and efficiency are to regularly clean or replace the air filters, ensure proper installation and sealing of ductwork, and schedule routine maintenance by a professional technician.
