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.

The easiest bottle ever and at an afforable price. The drop-in liners are a blessing when you're always in a rush (like me). The nipples come in three sizes (slow, medium and fast flow) so you can use these bottles as your baby gets older just by replacing the nipples. I bought a two-pack of fast-flow nipples for about $4.00. Replacement nipples and liners are available in many stores so they are easy to find. Target sells their own brand of 4 oz liners that are just as good as the Playtex brand...

Very very cute bottle but it has a huge flaw. I was instructed by my pediatrician to boil all nursing items for 20 minutes due to my daughter having recurring Thrush. I put this nurser in with other bottles my daughter had used that day because she touched the bottle repeatedly during feedings after having her hands in Thrush infested mouth. This nurser shrunk like a shrinky-dink! It shrunk to about 1/4 of it normal size. Strangest thing I have ever seen. Do not use/purchase this nurser/bot...

I originally purchased this system 9 years ago (before the nicer designer style came out)for my oldest daughter and I liked them so much.... that when my second child was born I used them again... I couldn't help it... I loved the fact that you could literally push all of the air out of the bottle... so I knew she wasn't consuming a ton of air and I liked the fact that she didn't have to lie flat in order to eat... which of course prevented liquid from draining down into her inner ears. As a r...

My daughter is breast fed mostly and trying to get her to take a bottle was next to impossible. She would gag and end up throwing up most of what she did manage to get down. These bottles are great for breast fed babies. We used Dr. Brown's at first and she still took in so much air she would cry from the gas pains. As soon as we switched to the Playtex bottles, she drank from them with such relaxation and didn't have any gas after. I got rid of all my other bottles and use ONLY the Playtex drop...

The best bottle hands down! I am an RN and I highly these bottles without hesitation! They are easy to clean, to travel with, to warm up, to feed baby... what else is left? My daughter ( now 4 months) was never gassy and doesn't spit up much at all ever! Good Luck!...

After buying all the rest, these bottles were the only ones that reduced gas, had a fast flow nipple that my daughter liked, and were big enough to hold 8 ounces of food. Tried all the other brands, and these hands down, worked the best. Drop - ins are extremely easy, and very little mess to clean up. Highly recommend this brand of bottle. ...

The nipples of these bottles let in too much air in the corners of my childs mouth. I wish I hadn't purchased so many after reading all the good reviews. I ended up swithching to Dr. Brown's bottles and really love them. Although the Dr. Brown's bottles have a tendancy to leak even when filled below the green line as directed. My baby doesn't get so fussy with them though as she does with the other bottles....

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 Love the origanel nurser so I tried theses new ones because of how cute they are; How ever the 'cute' curvy line and pictures around the numbers make it vary hard to accuretly measure the water. Also the new drop in bottle liners have clear numbers and lines. Put the two together and it's nearly imposible to see to measure the water. Playtex needs to fix one or the other....

I love these bottles! My son was picky about the kind of nipple we used and I could try 5 different kinds of nipples without buying new bottles. They are easy to clean and I love the sanitized liners. I tried the Avent and the Doctor Browns and he would have nothing to do with them and they don't have different kinds of nipples that go with the bottles. ...

I am a full-time working mom who also nurses. I used these bottles with my first child for 13 months (from the day I went back to work until he was weened), have started using them with my second child. Both took them right away and I have never had a problem with the bottles, nipples, or drop-ins. I like the clean, sanitary drop-in liner for each bottle. The slow-flow nipples are a good shape, texture, and flow for breastfed babies. Neither of my babies had any gas problems with these bott...

I used these bottles with my first child and I will definitly use them with my son who is due in 11 weeks! If you are a on-the-go parent with regular bottles, you'll have to stop and look for a water fountain to rinse out the old milk residue or milk that your baby did not finish before you can fill the bottle again. Or you may take 3 or 4 bottles with you which takes up too much room in your diaper bag. With these bottles you just pop in a new liner. They are collapsable and you can store 5 or ...

I was not impressesd with these bottles. As a first time Mom, I would see the commercials and ads and they always say "next to the breast there the best" so I thought I had to use them. WRONG! From day one my son did not do well with them.The bottles quickly fill with air when you put it down to burb even with the cap on and laying on its side, you have to squeeze out the air again and when you have a hungry baby who wants to wait? Even after pushing out the air several times he still would gu...

These bottles are great if you plan on switching between breast and bottle AFTER your milk is well established w/c typically takes about a month. The manufacturer even suggets to give this bottle to babies 1 month and up. ;-) This is the only bottle my breastfed baby takes and still uses! Easy clean up too! A+...

These are the best bottles ever invented. My sister has four kids, and none of the bottles she's ever gotten have had such super-soft nipples. When my sis tried to move one of her twins from breast to bottle, she litterally tried EVERY bottle/nipple they had out there and this was the ONLY bottle her baby would accept, anything else, her baby would scream and only accept the breast. these were a lifesaver for my sis. The design of the bottle is very cute too. I am about to have my first born, an...
