Tips given by Hunter Fan, I thought this was really helpful as a resource.

1. Measure the room where the air purifier will be used.

2. Click on the room size that most closely matches your room on the Air Purifier Selcection Guide.

3. Select the Hunter model with the CADR (Clean Air Delivery Rate)* performance rating to fit your room.

Things To Consider Before Buying An Air Purifier
How do you know that an air purifier is truly effective? Check the Association of Home Appliance Manufacturers (AHAM) seal on the package. AHAM independently tests and certifies air purifier performance. All reputable air purifier manufacturers display the AHAM certification seal, which includes the unit’s Clean Air Delivery Rate (CADR). CADR is the industry standard rating system for an air purifier’s effectiveness.

CADR: Real World Performance
CADR measures the amount of clean air that a purifier delivers into a room. It gauges real world performance, taking into account filter efficiency, airflow and room size. CADR is the single most important piece of information you need to make a head-to-head comparison of air cleaner performance.

What’s Changing?
Air Changes per Hour (ACH) is simply a measurement of how much air a unit moves, not how effectively the air is cleaned. Likewise, a filter’s “efficiency” measures the amount of particles that the filter material alone can capture in lab tests. These tests don’t incorporate real world factors like airflow design or fan speed. Remember, real world air purifier effectiveness is measured by CADR—not ACH or filter efficiency tests!

*CADR (Clean Air Delivery Rate) is an independently tested and certified measure of how effective an air purifier performs in the real world.

I was recently working on a press ad for air purification and came up with a more unique perspective of representing purification.

testsmall.jpg After working on countless press ads that had same ol’ company names and product line after product line, I felt like this artistic representation was a breath of fresh air. I got mixed reviews for it and hence am quite apprehensive about using it.

 

Those that didnt like it said because it was too graphic to represent a baby like this. Those who liked it, they said it was because it caught their attention and they felt compelled to stare at the poster for awhile.

I roll my eye-balls at society. tsk.

pollutants.jpgCarbon dioxide: Present in the unpolluted atmosphere at a concentration of about 0.03% percent but 5% of the air we breathe out is carbon dioxide so the level increases in inadequately ventilated occupied rooms. The level of carbon dioxide is therefore often used to assess the efficiency of ventilation. Outside sources include vehicle exhaust fumes or other exhausts.

Carbon monoxide: Produced by any process of combustion, including cooking and tobacco smoking. A major source of carbon monoxide is vehicle exhaust.

Formaldehyde: A colourless gas with a pungent odour. Found in hundreds of different products, including insulation material, ceiling tiles, particle board, plywood, office furniture, carpet glues, various plastics, synthetic fibres in rugs, upholstery and other textiles, pesticides, paint and paper. Levels of emission increase with temperature.

Ozone: Naturally present in the air since it is produced from oxygen by ultraviolet radiation. Can also be produced by electrical discharges and is emitted by some items of electrical equipment such as photocopiers and electrostatic precipitator devices used to clean the air by removing dust.

Most people don’t realize the gravity of indoor pollution. Heck, even I don’t take it seriously sometimes. When I hang out at a bar and I’m sucking in the smoking air, the various fibers, acoholic fumes, etc. everything. I dread to think of how polluted my body’s repiratory system is…

I was recently doing research on how operating rooms were set up in the past and wondered about its cleanliness, when I started reading about the oldest operating theater in the world in London, part of St. Thomas’ hospital (1822).

At the time when these public operating theaters existed, antiseptic and anesthesia had not been invented. Much of the surgeries that went on were mainly amputations because of the lack of antiseptic/anti-bacterial devices to prevent internal infections. It’s said that surgeons at that time could perform an entire amputation in under a minute to try and minimize pain and blood loss.

See the little box of saw dust underneath the table? That’s for collecting blood. Apparently most of the time the doctor’s coats were soaked with pus and blood that they became stiff!!

I think of the amount of bacteria that are allowed to grow and multiply, and travel through the air, I get highly highly grossed out. I wonder how many lives would have been saved with the difference of perhaps a simple ventilating mechanism or alcohol wash as an antiseptic. None of those existed for some reason.

ugh.

Interesting Find from Automobile Association of Singapore.

Air Purifiers these days are getting more compact and better looking, with more features like these portable ones. But how exactly do they compare in their efficiency?

Silent Air Purifier with Ultraviolet Germicidal Protection


The Silent Air Purifier circulates air-cleaning negative ions and can remove just about any type of airborne particle or pollutant, including allergens (e.g. pollen, pet dander, dust, ragweed), micro-organisms (e.g. bacteria, viruses, mold), chemicals and odors. It can be plugged into the wall outlets in your home, and also comes with a 12V car adapter for use in the vehicle.

Features:

  • Removable easy-clean grills. Front and rear grills slide off for easy cleaning.
  • Combines proven ionic air-cleaning technology with a germ-killing UV lamp.
  • Cleans and sanitizes the air 24 hours a day on just 8 watts.
  • No filters to buy or replace.
  • Ultraviolet lamp kills virtually all airborne bacteria, mold spores and viruses that enter the unit.
  • Neutralizes household odors.

SGD $99.00

Cordless Silent Air Purifier / Closet Anti-Mould Cleaner


Cordless Silent Air Purifier – A powerful room air purifier that keep mould out of closet!

Features:

  • Uses advanced ionic generation technology
  • Soundless design, no motor
  • Power Consumption: 3W
  • Easy to clean – NO filter replacement required
  • Dissolve and neutralize poisonous gases, bacteria & mould

SGD $59.90

For portable and small area use, these cleaners could come in handy depending on how reliable their “proven ionic air-cleaning technology” is.

I found their brand name to be Maier, with the supplier being a local Singaporean company that produces lifestyle well-being products. Interesting stuff they have. Cute and compact, but running or just 8 watts, I think it has rather limited capacities. Good thinking on the cordless part though.

I would like to hear from anyone who has tried Maier’s air cleaning products for some fair reviews.

Of late I have been researching the many varying air purifiers out in the market. In fact, I have actually used some of them before. I’ll say that the German IQAir purifiers (right) are pretty solid and not bad looking, but they are a little on the pricey side ($700 USD for a pretty mediocre sized unit).

However compared to most other air purifiers, I appreciate the quiet side this little baby produces. I never did get a particle count on the IQAir though. I was recently playing with Pyramid’s Trac Air Purifier (left) and ok, its not the prettiest thing, but darn!! This thing knocks my socks off!

You could start the room with 9 million particle counts and give this thing less than a couple of minutes and you got yourself down ot 0.004. That’s practically nothing. Ok so the Americans didnt come up with the prettiest thing but it does the job. I’m thoroughly impressed with this one.

Alright, let’s see what the Japanese have been getting up to lately. Japanese company Thanko came up with an ‘innovative’ one. The USB-powered Air Purifier using a silicon mask that aims to filter out allergens. According to Gizmodo.com, the apparatus is being marketed at $20

That’s a really ‘smart’ one guys. Only in Japan.
