Human flesh is the most common form of dust in the air, and makes up the bulk of what's known as “indoor air pollution”. So far, over 350 different types of indoor air pollution have been identified. Some common ones include pet dander, viruses, moulds, pollen, cleaning chemicals, and solvents from furniture, construction, and clothes.

Experts say that when children are exposed to large quantities of this dust at an early age there is a spike in the instances of asthma and allergies.

In fact, indoor air quality has become a hot topic over the past couple years with the discovery of “sick building syndrome”. This is a term used to describe the effects that moulds, viruses, and gases have on people who spend all their time in offices or otherwise indoors, and is responsible for all kinds of maladies.

Ultimately, the only real cure for sick building syndrome is a good dose of clean, fresh air. Barring that, there are many different air filtration and air purification devices on the market these days, each meant to eliminate the threat that indoor air pollution poses.

These are the best air purifiers available for your home or business. Make no mistake about it. They are made by a company with years of experience, that specializes in air purification. Unlike the infomercial company heavily marketing an inferior product, or the vacuum cleaner company that decided to 'get into the air purifier business'.

What types of particulate does an air purifier filter?

An air purifier filters dust, smoke, pollen, pet dander, mold spores, and other airborne particulate as small as 0.3 microns.

How does an air purifier work?

Dirty air is drawn into the air purifier through the inlet grill. Some of the units have a washable pre-filter that traps larger airborne particles. Air then passes through the carbon filter with help reduce odors and captures larger particles. The air then passes through the HEPA filter made of tightly woven fibers. Some units have electronic ionizers which further assist in particle removal. The fan then redistributes the filtered air throughout the room.

Before you buy a home air purifier

Indoor air pollution problem is a growing concern of more and more people. Not just out of curiosity. Fatigue, headaches, asthma, allergies, breathing difficulties, irritation of eyes, nose, and throat, high blood pressure, heart problems, poor mental performance - coming from various indoor air pollution factors - all cry for attention.

There are reasons why the indoor air quality problem has grown in last decades. First, due to energy conservation initiatives of the 1970s, new buildings are much more air tight, blocking the natural home ventilation of the incoming outdoor air. Without enough attention to ventilation, the air tight buildings conserve and accumulate carbon monoxide, radon, and other pollutants.

Dryer came as expected. Frys hair quickly without frozzoes thanks to ion setting. Volumizer not really worth it but it's included. Would buy another. Best hiair dryer I ever owned!...

Revlon RV544 1875 Watt Tourmaline Ionic Lightweight Dryer, Silver/Black Execelent, but a little too heavy. Good price....

I have curly, medium-length hair.I bought this dryer in the begining of the year thinking it would produce less frizz. After using it for 6 months (always on the warm settling, not hot), it fried my hair. My hair has never been this dry and unmanagable. Since the dryer was the only thing I changed in my hair-care regiment, I figured that was the answer. When I couldn't stand it any more, I started using my old non-ionic blow dryer. Within two weeks, I noticed my hair wasn't as dry and frizzy. I ...

I have owned this dryer for about 6 months. Over the last few months I have noticed the ends of my hair have been dry, frizzy and brittle. My hair has never been like this before. This morning while drying my hair, I noticed a bad smell and then saw clumps of hair with the ends melted together on the floor and bathroom counter. This dryer is a hazard and I cannot believe they are still selling them with all the other complaints I have read about them that date back to 2006! Don't buy this produc...

I bought this hairdryer thinking it did not have the ceramic function because none of the literature said anything about it, yet when the dryer arrived, the word CERAMIC was all over it. I was hoping to get the old dryer without the ceramic feature. ...

Until recently, I had never done any research before buying any household small appliances. When my Conair dryer finally died last week, I decided to shop around before making a purchase for its replacement. After reading other reviews about this dryer, I went straight to Target and bought it and I have been very pleased! I live in an area that has high summertime humidity and my hair is fine and tends to frizz a bit on the ends. The ion feature really does seem to work and since I've used this ...

I love this thing and I'm so glad I bought it! I used it this morning for the first time and found that it really did make my hair feel much softer than with my other, cheaper quality, hair dryer. After reading other people's reviews, I didn't know for sure whether I should buy it or not, but I convinced myself to because there will always be someone who's not happy with a particular product. But I'm happy with my purchase!...

I started out really liking this dryer but after a few weeks it would overheat within seconds and send out a spark that would actually burn my hair. It would singe it at the roots and burn off clumps of hair. Then it would be cool for a minute and overheat again. I didn't notice a difference with the Ion option but this is my first dryer with that option so I can't compare it to others. Other reviews seem to be great so I may have gotten a faulty one but be careful....

How does an air conditioner cool you?

An air conditioner is a piece of equipment that treats and controls the air temperature, humidity and cleanliness. It transfers heat and humidity from one space into another.

At the heart of every air conditioner is a compressor, which is a pump that circulates refrigerant through the cooling system. This refrigerant acts as a medium which extracts heat from one space and dissipates it into another. By circulating cool, dry and clean air through the room, an air-con helps keep you in cool comfort. The optimal temperature should be in the region of 24 degrees Celsius at relative humidity range of 55 - 65%.

What is a Compressor?
A compressor is the "heart" of the refrigeration circuit. It is a pump that circulates refrigerant through the system, just like the human heart circulates blood. This refrigerant is the medium which extracts heat from the room and dissipates it outdoors.

If you're reading this SYW, then a unit air conditioner is probably what you're looking for. It's the best kind to get if you live in a small house, apartment or studio, or if you've just added an extra room on the house and don't want to hook an entire system up to it. It's also cheaper (usually costing in the $150 - $250 range if you get it on sale, but more about that later). If you have a relatively large house that you want to get cooled quickly with the flick of a button, then you might want to consider getting a central cooling system, but this can cost you thousands of dollars.

I thought I had a fairly decent blowdryer...until it died. Now I'm glad the thing is gone. My hair is thick and has always taken a long time to dry. Thank you Revlon for cutting my drying time in half. My hair has a smoother texture and is much softer with this blowdryer. Since I started using it people have been commenting on how nice my hair looks. I was skeptical after reading the online reviews but after reading about the other blowdryers I decided to give it a try. I'm so glad I did!...

I looked at this hair dryer for two reasons: (1) as a back-up to my $100 hair dryer my salon sells and (2) something I could keep in my gym bag. I have long, naturally curly, thick hair that I like to wear very straight to the office. Both my expensive hair dryer and this hair dryer get my hair straight and very smooth. The best method for achieving this was to use the highest heat and fastest setting on wet hair until the hair is damp, then to finish drying my hair with the air-flow nozzle on l...

I read these reviews and thought I had found a miracle product. I have medium-thick hair, but it is long, and there is a lot of it. My hair is usually somewhat frizzy after blow-drying. I have used the Ion Stylist for over a week now, and have not noticed a difference in drying time. I have noticed a slight difference in the texture of my hair after drying, but I think that is due to the cool function on the dryer (better than most - cool air is expended almost immediately), rather than the ...

Can you actually love an appliance? B/c this dryer is great! I have long thick wavy hair and with my old dryer it took 30 minutes to dry, with this dryer only 15 minutes!!! Its so light weight my arm doesn't hurt. My hair is softer after one use. I used to hate drying my hair, now I look forward to it. If you are looking for a dryer just buy this one, its absolutely great!It delivers everything it promises. You'll love it....

I just bought this dryer so I have yet to use it. I just wanted to thank all the ladies for their reviews. It helped me choose this dryer. I have been using the Conair 1875 translucent blue dryer for two years. I had to buy a new one each year why? good question, b/c it stops working. I used it last night, and went to use it this monring and ah ha, it doesn't work! It didn't fall noone else uses it it just stoped! I was going to but the Conair ion blowdryer but after reading all these reviews ...

I was a little skeptical about the reviews that I read. I had doubts of how a blow dryer can give you shine and reduce freeze, and what was this ion thing. Well, for someone who has two left hands for blow drying her hair this blow dryer is a God's sent. I blew dry my hair with this brow dryer and with the next time I had to wash my hair I dried it with my old blow dryer. For someone who lives in Miami, Florida and where humidity is 1000%, this blow dryer works amazing. The blow dryer del...
