Thanks Carl, I will make note. I like easy. I appreciate you explaining it to

me. Loni

In one sense, air filters are actually very simple. All you need to

know is the size of the holes in the filter. A HEPA filter makes it

easy because they are always 0.3 microns. That means any particle 0.3

microns and larger will be stopped, like sifting sand through screen

wire or rinsing berries with a strainer. The berries stay while the

water goes through.

Almost all particles of concern are 1 micron or larger so a HEPA is

sufficient. If it isn't a HEPA then it either doesn't remove small

enough particles or it is " pretend " disguised as " new technology. "

As for the math, I apologize for the confusion including the errors.

The errors are really insignificant because the main point is that

there is a precise way of calculating how much air a filter needs to

move for a specific room and how often you want the air to go through

the filter. The more times you want the air to go through and the

bigger the room, the bigger the fan. The bigger the fan the higher

the cost and the more noise. Forget my confusing math and look at the

chart on the box for the filter.

As for other ways of cleaning air, there really aren't any. Besides,

filters are really a final step, not the first step to clean air. If

you want cleaner air, the following actions are in order of most

effective to least effective:

1. Remove the source. The contaminant is gone which means there is no

exposure. It is no longer in the air so you don't need a filter.

2. Isolate the source. It is still there but it can't get to you. A

sealed moisture barrier in a crawlspace for example, pet dander on

walls that are vacuumed and then painted. Most is removed but what is

left is behind the paint and you aren't exposed. Note: it is true for

a light dusting of mold spores and fragments but not for mold growth.

3. Dilute the source by ventilation. It is still there but the

exposure is decreased because it is mixed with more air. Especially

effective with chemicals, not so effective with particles because

many are too big to stay in the air.

4. Reduce the source by filtration. It is still there but portions of

it are sequentially removed IF it goes through the filter.

It's like removing mud from a flooded basement. First you need

shovels to remove the mud, then brooms, then vacuums, then Q-tips.

Air filters function more like Q-tips than shovels.

No, but maybe I will give it a try. Most vitimans seem to do nothing

for me at best. I hate swallowing pills. I try to eat a ballanced

diet but that is a problem in it's self becuase I seem to react to

food a lot of the time.

I won't eat carrots or celory or lettuce that has been in my fridge

more than four or five days becuase I am starting to think that the

slim or bacteria that grows on produce makes me sick.

After ten years of being sick I have come to the conclusion that the

things I react to are almost always organism's. Dust, Dust mites,

mold, bacteria.

HEPA filters will remove the physically larger particles from the air.

They work like a sieve, which doesn't have anything at all to do with

mycotoxins. Some research indicates that smaller particles have higher

toxicity by weight, I think, so thats something to be concerned about! The

particles that cruise through the HEPA filter may be the most dangerous to

your body because of their small size. The same issue exists for masks.

OTOH, filtration IS helpful in emergency situations when elimination

(physical removal of all mold) or dilution (letting in lots of fresh air to

dilute any particles in the air) is not available. But the smaller

particles (the ones the filters don't filter out) are also the ones that

go the deepest into your lungs! The most dangerous. Brand name has nothing

to do with that ability, in that all filters are the same, except that

different filters may be different in their pore sizes and ability to fiter

out some VOCs (some filters have activated charcoal, but that activated

charcoal's ability to fiter out VOCs doesn't last very long in a high VOC

situation)

I am not an expert on filtration by any means. It is useful for people in

situations where they need to reduce the amount of particulates in the air.

But they might also be dangerous in the sense that they might induce in

people who are using them a false sense of security in a dangerous

situation. If you keep that in mind, you'll be better off in the long run.

As far as UV light, honestly, I don't know UV light's effect on mycotoxins.

I suspect that UV light is effective mostly in killing some viable bacteria,

viruses, etc. I don't think that the oxidation effect of light even kills

all bacteria, either.

As far as lights? The sun emits strong UV light, MUCH stronger than any

light fixture. Putting objects in bring sunlight for several days is known

to reduce the reactivity to people of mold on an object. If a manufacturer

is making claims for a product, there may be some EPA regulations that they

need to follow. There might (I would think should) be more information on

the EPAs web site about specific products, which could be looked up perhaps

by the manufacturer.

Mycotoxins I think can be much more durable than bacteria. Some mycotoxins,

like trichothecenes, are incredibly resistant to deactivation and again, I

think its prudent to assume that unless you hear from a reputable authority

on a particular kind of mycotoxin (people like Dr. Straus at TTUHSC

for trichothecenes, for example) that a particular decontamination strategy

is effective for that substance) I would assume as the default that it does

NOT reduce its toxicity to be safe. So a filter might reduce the amount of

particles, but the particles remaining might be more toxic, by weight. (but

there would be less of them) and more able to penetrate deeply into the

lungs, on the average. In practice, in a severe mold environment, you would

probably get some relief, but not enough to make a situation safe especially

if you spent a lot of time there. Better to remove the mold itself if

possible.

I hope that I wasn't too annoying explaining this. I don't guarantee its

100% accurate, but I think its fairly close.. Non-experts like me may know

the mechanics somewhat but there are some legal definitions involved with

stuff like this.. I can't explain them as I don't know the acronyms and

specs they use..

Pat and LiveSimply,

No particles " cruise " through a HEPA filter. Even at the size of .3 micron

the least-efficiently trapped particle size), 60-70% of the particles are

removed by a HEPA filter, so on multiple passes through the filter, air in a

room would be cleaned by a HEPA air cleaner having a significant air flow.

Because the mechanism for filtration (means by which most particles are

trapped on the filter fibers) shifts around .3 micron, particles smaller

than .3 micron are actually trapped MORE efficiently, so a much greater

percentage of the smallest particles is trapped. Thus operating the filter

certainly does NOT make the air less healthy to breathe.

Filtration is certainly a temporary option for air cleaning but ALWAYS,

source removal is the first step.

Germicidal ultraviolet lights (and even tanning lights) can be far more

powerful than the sun's rays and can be purchased, but these are mainly

biocidal and at typical strengths might kill bacteria and viruses but would

have no effect on mycotoxins (though in a lab, high-energy UV irradiation of

gases and molecules solutions is a very common method of bringing about

chemical change).

Nonetheless, putting items in the sun to air out is a fine method for

eliminating all sorts of problems; more importantly, the method is free and

safe.

A HEGA (gas) filter is not necessary and to be honest, if the fan noise

isn't a problem, you don't have to spend over $200 for a decent air

purifier.

Jeff, did it seem like I was saying that the filter made it less safe to

breathe? I didn't mean it that way at all but I could see how it might seem

so.

What I meant is that many people might be tempted to see the use of a filter

as substituting for getting rid of mold or removing themselves from an

uncontrollable situation and that that was not a good long term strategy

because the filter

was not as good at removing the smallest particles as the larger ones. (at

least on the first go around)

I HAD forgotten that the *multiple passes* are important to doing that..

Also, I had never heard of a HEGA filter at all..

Thank all of you!

Hi Jeff!

Thanks so much for the info. You're a wealth of info and your book is

wonderful. I thought that the HEGA filter would rid the house of the

musty smell that emanates every now and then from who knows where. You

just saved me some money. ;)

They are recommended by the Environmental Health Center in Dallas,

I am told.....Dr. Rea. Josie

How do you like them? Are they heavy? I know you have to turn them

upside down to replace the filter.

How much do the consumables on these filters cost and how often do they have

to be replaced? I'd guess that for people with mold hypersensitivity, they

need to be replaced more frequently than the manufacturers recommendations.

So, maybe having a few mainstream (~$200-250) high capacity consumer-grade

HEPA cleaners might be a better solution at a lower price than one or two of

these hyper-expensive premium brand units? Because you could move more air

through them at a lower unit cost. I think that is what Jeff was getting at

the other day.

A buyer should look at the square footage that needs to be cleaned and then

the cost of all the consumables, prefilters, etc. over time.

Another option would be balanced, powered ventilation. (HRVs or ERVs) A

caveat is that I currently have no personal experience with these units and

some well-informed people have told me that they can be problematic if not

maintained well, but they also offer an option not available with

filtration, continuous fresh air that is warmed (with your outgoing air) in

the winter and cooled (in a similar matter) in the summer?

For example, Panasonic has a new unit that looks very affordable compared to

most I have seen. It installs like a bathroom vent fan (except that it has

two vents to the outside instead of one) . Its a reputable vendor that has a

track record and looks like a good option for people in coastal climates

that don't get too cold. (it then has to defrost the core) It all depends on

the kind of issues you have.

I think fresh air is more desirable than filtered air in almost all

situations.

The Panasonic I think has washable filters.. Its not an air filtration unit,

its a heat exchanger/ventilator. A completely different animal.
