Ultraviolet Air Purifier
One of the potential air purification methods you should take a look at is an ultraviolet air purifier. This method is often used in conjunction with several others, because it doesn't really get rid of any dirt or junk in the air in and of itself. The UV method is geared solely towards killing germs. Essentially, a UV lamp is installed inside the air purifier and is used to radiate all the air coming through it. This kills off the bacteria in the air as it passes through, and when the air comes out there will be a lower concentration. If the main reason that you're getting an air purifier is because of a medical or immune system issue, then you need to make sure that this is installed in your system. It's also just generally good for other people as well who are worried about germs or getting sick.

Ultraviolet Air Purifier
One thing that you should be wary of is that if you're going to buy an ultraviolet air purifier, you need to be 100% sure of what the specific specs are on the brand you're looking at. The big problem here is that there are essentially two uses for the ultraviolet lamp - one is to do what is described above, killing the germs directly. The other is to generate ozone, which indirectly can kill germs. However, ozone as a gas is harmful to humans and there is some dispute about whether an ozone air purifier is safe or not - there can be harmful gas pockets in your house near the air purifier, and it's probably better just to avoid it. So make sure to read the descriptions carefully - look for the word ozone anywhere on it. You want an ultraviolet air purifier that just shines the light at the germs, you don't want it to do anything else.
