Are air purifiers a joke?
I have 2 large air purifiers in my room and a small one. One is a big HEPA which is rated for a room much bigger than mine and the other is an ionic one that seems to collect some dust. I keep my door closed all the time to keep dust out.
I still notice dust floating in the air when i look at light hitting the air. Are these purifiers even practical? Is it possible to eliminate all of the dust in the air?
I have one air purifier in my room and it gets dusty outside even though it is pulling air into itself. The problem with ionic air cleaners, from what I have read, is that it makes the dust heavy so it falls out of the air. Thus, it will fall onto you. The air purifier will suck the dust into itself and catch it in its filter. I bought, and had to take back, an air purifier that sucked in dust and dropped it on the floor inside of the machine because there wasn’t a bottom. That I couldn’t figure out.
We had our ducts cleaned, but I know that they don’t go into every nook and cranny. Look at your cold air return vents and see the dust that collects on them. We have carpet, a cat, and cotton curtains, and I don’t dust or vacuum nearly enough, so the room is usually dusty.

From: wikipedia: http://en.wikipedia.org/wiki/Dust
Dust in homes, offices, and other human environments consists of human skin cells, plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil and dust, and many other materials which may be found in the local environment.[1] The precise composition of domestic dust can vary widely:
Make sure you clean or replace your filters frequently and that you have dust mite barriers on your pillows and mattress. I got mine at Target as suggested by the assistant in my allergist’s office. I guess we’ll have to vacuum more if we stop dust mites from eating the skin cells that drop off of our body. Their feces is what we are allergic to.
Dust comes into the room and the house through any place where air can come in. There is probably a gap between the bottom of your bedroom door and the floor. I remember during dust storms in Texas that even inside school, the grit would get into our mouths. We would have to clean the home ec kitchen before and after we cooked on those days.
Dust is mainly created from your skin, so unless you are never in the room, there will always be small amounts of dust. Dust in human and pet skin, small particles of sand from the middle east, mites, and mite feces.

No, they are not a joke. Remember your air conditioning is on, and dust is circulating through your whole house. Have you replaced your home’s air conditioning filter lately? Like once a month. Have you had your home’s vents cleaned? Even the correct size air purifers will not take all the dust out of your room, especially if you have carpet, drapes, and other dust catchers like stuffed animals, and the real animals like dogs, and cats. Also, I have allergies, and I have noticed that different brands work better then others. No it is not possible to eliminate all of the dust in the air with air purifiers. You need other dust abatement efforts. Perhaps you can return the air purifiers and try another brand.

They help but to get rid of everything (or almost everything as everything is wishful thinking) you have to basically build a clean room. You have to have the air Hepa filtered and a laminar (ceiling to floor) flow. Air filtration has to be 100% and an airlock for entering and leaving the room. The rooms are rated by no. of particles per cubic centimeter as measured with a particle counter. A class ten room (amazingly clean) has 10 particles per cubic centimeter and a class one (1) room is the best you can get. Wearing regular clothes in there is a no no. Only clean room suits with booties, gloves, hoods and face masks. Really not a place one would want to live.
