How helpful are air purifiers?

They are very helpful, but it depends on which brand. They are an investmtent and a $30 unit from wal-mart will only be a waste of money. I advise you to do research on different types and find which is best for you. Some are better for reducing smoke odors and other odors. Others are better for reducing household allergens such as dust mites, pollen, pet dander, etc. The type that you buy really depends on the problem you are trying to solve by using the purifier. They are great as long as you have the right one.

an air conditioner helps to maintain the room at  ambient conditions suitable for human comfort by monitoring the parameters like humidity,temperature,dust etc where as a refrigerator keeps the temperature within the system lower than that of the surroundings by using 2nd law of thermodynamics.

In the winter when you have the heater on, the air can get pretty dry , that would be a good time to use a humdifier.\n\nAlso, if your baby gets a cold humdifier can help a lot

From what I've always understood, dry air is better for asthma, making a dehumidifier better for one.

Ecolab is a client of mine. I sell them janitorial supplies. A friend of mine also works with them. They seem to be a profitable company.

First of all, be sure to be there when they do the job!  We had our ducts cleaned and got robbed by one of the workers who thought we wouldn't miss a few "minor" personal items.  But, even though they didn't believe us at first, we reported it to the police and the company and he got caught!\n\nSecondly, ask if they not only remove the vent covers but clean those too.  Ask how they clean them and if they use their own cleaning supplies and take the vent covers outside to clean--not in your bathroom or kitchen sinks, using your personal towels.  Ask if they clean up the lint that falls into the room with a vacuum cleaner.\n\nThey should have a crew of at least two people to put the hose in and clean out the vents and one to clean the vent covers and the area around the vents where the lint falls.\n\nThey should clean the air intake vents and cover also.  Some try to sell you on cleaning out your actual AC/HVAC unit coils.  I don't see the need for that, but if they insists it is needed, get them to show you the dirt in there that they will be cleaning out. If they can't show you, chances are they will not be able to get in there to clean it.\n\nThey should change the air filter, but be sure they don't try to sell you some heavy-duty, life-time guarantee filter that supposedly never needs to be replaced.  Those don't let enough air flow through.  The medium grade ones changed every few months or so work the best.  You can buy those at a home improvement store and change them out yourself during the year.\n\nMake sure that they don't damage your walls with their big machine, trying to get it down the hall and around corners.  They damaged our walls, too and we had to have them plaster and paint it again.\n\nJust because the company has a nationally recognizeable name doesn't mean they will do the best job. Often these are owners who hire flunkies to do the work who are thieves and don't care.  It would be better to get a local guy that has been doing it a long time and can furnish you with references of satisfied customers.

I agree with the previous answer, while ozone is a powerful cleaning agent, it has also been proven to be harmful. I am a certified Indoor Air Quality professional and I recently wrote an article about things to consider in a home air purifier: \nhttp://www.breathepureair.com/airqualityblog/residential-air-purifiers/\n\nYou may also want to check the Maerican Lung Association, which also has a section titled "Problems with Ozone"\nhttp://www.lungusa.org/site/pp.asp?c=dvLUK9O0E&b=39289\n\nThe EPA also has some great information on their Indoor Air Quality Fact Sheet: Ozone Generators that are Sold as Air Cleaners: An Assessment of Effectiveness and Health Consequences:\nhttp://www.epa.gov/iaq/pubs/ozonegen.html\n\nThe Canadian Center for Occupational Health and Safety also has a published report about the negative health effects of ozone:\nhttp://www.ccohs.ca/oshanswers/chemicals/chem_profiles/ozone/health_ozo.html

98 % is but there r also air born diseases and viruses that r caught not by touch but from the air.If someone ate in a room with someone who had an airborn virus you would get it.I know this from experience.Hand sanitizer is good to take anywhere especially buses and when handleing money.

The vast majority of air conditioning systems do not purify air.  There are a few that do however.  Some air conditioning units are equipped with HEPA filters.  These filters filter out quite a lot of small particles.  Some use activated-charcoal which is able to chemically react with many potential toxins in the air.  Others use UV light inside the air conditioning unit in order to break down particles of pollen, viral particles, bacteria, and fungi.  I am unaware of any that can remove CO2, but there are some that can probably remove CO.  Some do unfortunately produce ozone.\n\nThe units that use UV light can produce ozone, and sometimes can even blacken walls where they pump out air.  Some filters use charged plates to capture charged particles in the air.  These charged plates can also cause the formation of Ozone.

The only thing I can suggest is a ozone generator, I know it can kill odors, fungus, viruses and bacteria. It is a strong oxidant ans may work.

I am not a filter expert but I do know if you have asthma you Do Not want to run a humidifier....."bed bugs" and other micro scopic allergans live off of the humidity in the air, carpet, clothes, ect.... causing asthma symptoms to become relentless.So while you are at the store picking up a filter, I would also buy a humidity monitoring device......Humidifiers, when not cleaned properly can also release pseudomonas....a bacteria that can keep your whole family sick without be detected.......good luck

Use a good air purifier with a hepa filter, good filters for your central air unit, and remove all carpeting from your house since carpet is the worst to trap dust and allergens.

A number of stages is necessary:\n\n1. Filtration - To remove particles, can be any filter.\n2. Odor removal - Use charcoal\n3. Ultraviolet treatment - To kill most germs\n4. Reverse osmosis

By a hepa filter vacuum cleaner.  Change the furnace filter regularly.  Plastic cover for mattress prevents dust mites.  There are also vent filters for the room vents.  Avoid large drapes and curtains.  Vent the air with a fan often and if you are really serious..buy one of those ionic air purifiers.  This all worked to make my house more comfortable for my daughter.

There is no good answer to this problem since Mexico City has some of the worst air pollution in the world.  You can stay inside, preferably with a filtered air conditioning system (most office buildings use these), and go outside only when air pollution is less (check pollution reports, windy days).  Also, if asthma is the problem, consider other ways to control your asthma.
