How would it help the Earth if they invented big air purifiers?

Like not ones that go in your house, because, they already exsist. I mean if they invented ones that were as big as an electrical post in a city. How would this improve the air?

It would remove the toxins found in the air, but what help would they really be if the air is CONSTANTLY being being polluted with cars, factories, etc......?

How can I get the smell of smoke out of my apartment, do air purifiers work?

I think I just had some neighbors move in that must smoke a lot because it smells incredibley strong when I walk into my apartment. I guess it must be leaking through the walls I dont know how else it would be happening. What can I do about this? Do air purifiers work, I really dont want to spend a lot of money

The real use for an air purifier is to remove harmful particles from the air. Mold, mildew, pollen, dust...

Yes, they will remove a bit if the smell from smoke and pet odor, but I am not sure it would be enough to help that problem in itself.

They are still a great addition to your home if you do not have one! I would strongly suggest you add it as it can't possibly hurt and could help your lungs.

I'm allergic to cats and just got a kitten. I've been taking Claritin, which seems to help. I was wondering though, do air purifiers really work for pet allergies or are they a waste of money?

If you're allergic to your cat, it's probably the dander that's causing it. Just like a human's dandruff, pet dander are flakes of dead skin. So, it all depends on the air purifier. There are some air purifiers that work better than others.

I recommend looking at the line of air purifiers that Oreck produces. They've always had good quality in my opinion, and any extra money you pay for them now is saved in maintenance and filters later. And I think the comfort is well worth it. Also, Oreck is one of those companies that puts a small amount of ionized air out, which makes your air smell nice. Yes, there are studies that say too many ions are bad for your health, but that only means that you shouldn't sleep right next to them.

I looked for "pet allergies" in WebMD, and came up with this: http://www.webmd.com/content/article/113/110883.htm

I think its a way to increase sickness, seeing as how air purifiers actually make you healthier and therefore less people are buying medicine, which would explain the need to ban it and regulate access to health by doing so.
The one in the papers and on the news. I think its a way to increase sickness, seeing as how air purifiers actually make you healthier and therefore less people are buying medicine, which would explain the need to ban it and regulate access to health by doing so.

What ban? That's a new one on me. If there is one, there you are right, more people ARE gonna get sick because of the germs lingering in the air.

Would air purifiers help with animal hair and dust in the air?

Is it worth the money? I have a new baby and she is getting stuffy and I think it may be the air

Yes, air purifiers can really help with removing the animal dander from the air, and to improve overall air quality in the home. However, you still need to vacuum and dust regularly to remove any hair that has settled on surfaces.

Place the purifier in areas that are particularly troublesome to ensure that the purifier is close enough to suck in the unwanted hair particles etc.

I recommend that you get advice from your doctor before using a purifier to ensure that the stuffiness is not being caused by another medical condition or allergy, and also to check which is the most suitable type of purifier for your daughter.

How effective are the Ionic Pro air purifiers? And are they effective at removing cooking odors?

I have an ionic breeze, it awsome. When its a good one and its kept clean it'll get rid of ANY orders.cooking or smoking. they do work and work great,it your wiling to spend the money for a good one.

Both of these previous answers are simply untrue!

For the ultimate in air filtration, a true HEPA filter (one that passes all of the air in the house through it by installing inline to your HVAC system) is the best choice. It uses the type of filtration technology required in hospitals and operating rooms. HEPA filters are the most efficient mechanical filters for removing small particles which can be breathed deep into the lungs. HEPA filters have a 99.97% efficiency for particle sizes all the way down to 0.30 microns.

The vast majority of the odor and unhealthy particles in the air are smaller than 5 microns, and these smaller ones are generally more detrimental to your health, so it’s important to remove those by using devices like a HEPA filter

When talking about odors, almost all major odors in a house are 0.30 microns and above. These contaminants include:
Pollen, mold, plant spores 7 - 70 microns
Dust mites 3 - 10 microns
Hairspray 3 - 10 microns
Large bacteria 1 - 20 microns
Auto emissions 1 - 3 microns
Lead dust 1 - 3 microns
Fungal spores 0.50 - 7 microns
Cooking smoke/odors 0.30 - 1 microns
Paint pigments 0.30 - 1 microns
Pet dander 0.15 - 8 microns
Small bacteria 0.08 - 1 microns
Tobacco smoke 0.008 - 0.6 microns

So as you can see, The HEPA filter removes almost all of the major casues of odors in a house.

As far as "Ionic Air Cleaners," you need to know recent studies Studies by the scientific community and a leading consumer publication have demonstrated that these devices do a poor job of filtering and cleaning the air, and even worse, they can generate possibly unhealthy levels of ozone!

Independent studies have shown that ionizing air cleaners are not effective in cleaning the air and improving indoor air quality. Despite the manufacturer’s claims, all the models tested received ratings of “Poor” for removal of
dust, smoke and pollen. The ionization process (which generates ozone) is often touted as the key to removing indoor air contaminants. There is considerable scientific evidence that demonstrates that ozone has little potential to remove contaminants at concentrations that do not exceed public health standards. These units also lack the ability to move adequate amounts of air for thorough filtration.

While the ozone layer in the upper atmosphere is beneficial and protects us from harmful ultraviolet rays, at ground level, ozone is an irritant that can cause decreased lung function and aggravate asthma. In fact, the EPA refers to ozone as “Good up high— bad nearby”.

Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. At ground level it has another common name you may know: smog! Independent tests have confirmed that ionizing air cleaners can produce levels of ozone 5-10 times higher than public health limits!!

Based on the available scientific evidence and independent reports in noted consumer publications, the ability of these devices to clean air is very low, and much less effective than other filtration products on the market today. Further, the potential health risks associated with the high levels or ozone generated make these products questionable at best, and possibly even detrimental to human health. The American Lung Association suggests that ozone generators should not be used.

I'm living in a new apartment, and I recently checked the carbon monoxide level and it showed 268. This seemed a little too high, and I wondered if air purifiers reduced the amount of carbon monoxide in the air. Does anyone know? Also, if they do, can anyone recommend a good purifier to reduce the carbon monoxide? Thanks.

Fresh clean air coming in is good but the old stuff has to get out, perhaps a small extractor fan?
On purifiers avoid the ozone kind, they can harm the lungs.

Do Air purifiers really work? How do they work? Which one would you recommend?
