Consumer Alertope体育客户端oope体育客户端s

Air Cleaner buyers face a maze of advertising hype and questionable marketing practices.

ope体育客户端u often emphasize selling points in a one sided manner.

Here lie both danger and opportunity.

The danger may go beyond just wasted time and money: some air purifiers are actually unhealthy.

A perfect opportunity to improve our health and well being also exists. I believe we can all benefit from a plan to improve indoor air quality, which includes carefully chosen purifiers.

The majority of people buying purifiers have wasted their money, naively buying over-hyped products they saw on ope体育客户端n. Many of these folks go straight from viewing the TV ads to the purchase without careful product comparison.

Many air cleaners have been sold via ope体育客户端, although MLM is currently in decline.

Machines sold through these marketing channels do little cleaning and even less to improve health.

The ads cost millions, so the consumers pay even more for the “stylish" products.

Give these vendors credit for running a clever marketing campaign, but don’t give them your credit card!


A second group of buyers researches diligently, only to be lead astray by ope体育手机客户端 which is deliberately spurious, misleading, offers an incomplete view, or is simply incompetent. laptop lady

They enter "air purifier reviews" into their favorite search engine, looking for information.

Their search lists ope体育 手机客户端 with a bewildering array of makes, models, and cleaning technologies.

The vast majority of these products lack the market penetration required for deep and broad ope体育客户端a and reliable ope体育客户端u.

While there are many good purification vendors and honest air cleaner reviewers, clicking most search engine results is an annoying waste of time.

Worse yet, most "reviews" are posted on sites selling the air cleaners they rate the highest. Some even have ope体育客户端a in the machines their site evaluates.

In recent years, former marketing-over-substance leaders Oreck and Sharper Image have fallen by the wayside, but the rise of ope体育客户端i, most rebranded with only cryptic product background, has kept the consumer in the dark.

In the recession of 2009, many dealers closed, hundreds of models were discontinued, support evaporated, warranty claim payouts shrank, and replacement filters dried up.

Buyers should beware "deals" on ope体育客户端y equipment and obscure builders/vendors.

These are then re-engineered for mainland China manufacture and reintroduced in the US market as the familiar brand.

Deliberately obscure jargon abounds in air cleaning world, with confusing acronyms everywhere; ope体育客户端l and more.

Let’s work smarter and harder. It's time we cleaned the air along the Information Superhighway.


ed sherbenou

My name is Ed.

I've been a ceaseless campaigner against ope体育客户端m most of my adult life.

My detailed knowledge was gained the hard way: through a 40 year struggle against multiple chemical sensitivities (MCS), chronic fatigue (CFIDS) and Fibromyalgia.

I smell an idling diesel, a cigarette, or excess perfume on either gender, from far away.

I must avoid these ope体育丨客户端, just to keep the health gains I have made.

My first attempt to purify air was a simple ionizer, mail-ordered from the then-embryonic Sharper Image, after viewing a glossy 1977 magazine ad.

I bought my first purifier without any ope体育客户端o - there were literally no consumer resources dedicated to air quality, and the internet didn't exist.

There were no air purifier reviews.

But there was a universal belief, cultivated by propaganda since the 1950's, in "progress through chemistry".

This blinded many, especially in the scientific and medical institutions, to dangers that common sense should have revealed.

Since that time I have learned a key truth about wellness, which is what makes this site different:


I believe that allergy, asthma, MCS, and many other health problems have ope体育 手机客户端.

Everyday exposures to unseen pollutants in our air, water, and food, as well as rapidly evolving microorganisms, are more important than the dust we can see and odors we can smell.

Everyone has seen dust particles dancing in a shaft of sunlight in their home.

The dirty little secret of the industry is this:

Most purifiers cannot completely remove fine lung-penetrating particles,
lingering odors, toxic volatile gasses, or secondhand smoke.

So much of the air cleaner industry concentrates on products which simply make things look clean by collecting large sized particles - ope体育客户端r

Hey, any average HEPA-filtered ope体育客户端i

And this leads us to the second important insight - a HEPA filter is expired when it fills with enough particles to obstruct airflow, not when it is simply discolored or an arbitrary time limit is reached.

HEPAs are designed to retain tiny .3 micron sized particlesope体育客户端g.

If we have poor prefiltering, as many inexpensive air cleaners do, the main filter will fill rapidly with 5 to 20 micron large dust and need frequent replacement.

This allows lower quality air cleaners to be sold as ope体育客户端fope 体育客户端

Many of these bargain air purifiers have long term costs of ownership higher than some premium marques.

The third key to air purifier success is discount the industry's room size ratingsope体育客户端i, falsely believing this is economical.

Installed in too large a spaceope体育客户端eope体育客户端e

Together we can see beyond the industry's smokescreen and seek effective solutions to these unseen dangers.

A systematic approach, starting with locating and removing pollution sourcesope体育客户端d, as well as adequate ventilation, should accompany the use of air cleaners.


We need to analyze what's ope体育客户端d, beyond the stylishness of a typical plastic case, which gets the emphasis in most reviews.

In the photo, I have disassembled a favorite air purifier, a 2005 model Sharp Plasmacluster that still runs perfectly. air purifier

It's air purifier cleaning time, and the arrows show accumulated dirt.

The blue arrow points to the dusty washable carbon filter bag, red to the air cleaner's permanent prefilter, and yellow to the still-clean HEPA filter.

This air cleaner has run every day since 2005 without needing a HEPA filter replacement.

To control operating costs, I have refilled the carbon filter bag ($15) and keep coarse visible dust out of the HEPAope体育客户端e.

Again, the "secret" to long HEPA filter life is keeping particles above 5 microns, large dust, from filling the gaps in a filter intended for tiny sub-micron particles. amazon side ad

I do this by modifying the filter train, adding extra prefilter layers when I think the purifier is built well enough to handle the load, and cleaning all the prefilters frequently.

Also, examining the area around the fan reveals no accumulation of fine particles, indicative of a quality air cleaner (minimal HEPA filter bypassingope体育客户端o).

Most air purifier reviewers provide what is essentially a sales brochure.

For some lower sales volume air cleaners, it's hard to find more.

Some air purifiers and other products are presented here without the name "review."

These are called ope体育客户端s and generally represent shorter, less detailed information on slower selling models.

But where there is real data to review, digging deep through web search results and online buyer reviews will uncover it.


A marketing fiction concerns so-called testing of air cleaners.

Both AHAM's ope体育客户端k.

I cannot buy every air cleaner, or conduct "laboratory" tests.

I am using a Dylos DC1100 "for air purifier test" laser particle counterope体育客户端i on products I have on test.

This $350 laser counter is a great tool for consumer-level indoor air management.

Use of the particle counter has opened my eyes to another secret - ope体育 手机客户端.

This means that many sensor-driven automated systems, when run in "AUTO" mode, are ope体育客户端gope体育客户端o

This is why I recommend every air purifier be installed in less than the manufacturer's recommended room size and ope体育客户端d
