What Does Pore Size Mean in Allergy Proof Bedding

If you are diagnosed with dust mite allergies, the doctor will tell you to encase your bed in dust mite proof covers. That’s great advice. But, it isn’t all the information you need to make an informed buying decision. I know. That’s because we field lots of calls from people that want to know about pore sizes, microweaves, and laminated or coated allergy proof bedding. They are confused and looking for answers. We’re here to help.

The doctor tells you to use allergy proof bedding because it protects you from allergens that are too small to be seen. Dust mites, dust mite feces, bits of pollen and animal allergens collect in and on fiber surfaces. Your mattress, pillows, duvet or comforter are all places for allergens to collect.

Allergy proof bedding puts a barrier between you and the allergens. If you can’t breathe the allergen, it won’t make you sick.

As long as you wash your sheets every 7 days in 140ºF water, allergens won’t build up on top of your allergy covers.  The special zippered covers and the hot water washing keep the allergens at bay.

So, now we understand why we need allergy-proof bedding, but what is it that makes bedding allergy proof?

There are two ways to approach making a fabric allergy-proof: laminate it or weave it tightly.

Laminated fabrics are just a traditional bed linen fabric that has been bonded to a material that makes the fabric impenetrable to allergens. These fabrics can be cotton, synthetic, or a blend of the two.  It’s not the fabric that is allergy-proof, it’s the laminated backing. The laminate is some form of plastic. Heats bonds the plastic to the fabric.  Laminated fabrics don’t depend on the fabric to provide protection; they rely on the laminate. Laminates don’t have a pore size.

Microweave fabrics provide a barrier that allergens can’t get through. That’s because they have a very tight weave. The space between the fibers used to weave the fabric is the pore size. The larger the pore size, the more allergens that can get through. The smaller the pore size, the more particles the fabric can stop.

Effective Pore Sizes

The pore size is determined by how tightly the fabric is woven.  Natural fibers like cotton are not very strong. You can’t weave cotton tightly. Polyester is a very strong fiber. It’s perfect for tight microweaves.

Allergy proof bedding with the smallest pore size will be all polyester. All cotton allergy proof bedding will have a larger pore size. Cotton/polyester blends are in the middle when it comes to pore sizes.

Dust mite fecal matter and/or body parts (we don’t actually breathe in whole dust mites) are as large as 10 microns. Pet allergen and mold spores are about 3 microns. In order for a microweave mattress encasing to be effective against dust mites it needs a pore size of 10 microns or less and 3 microns or less to be effective against mold and dander.

With that being said, all laminated mattress encasings are effective against dust mite, animal dander and mold allergens because they are a total barrier. They are water-proof too.

Differences in Allergy Proof Bedding

Microweaves and laminates are both effective in protecting against allergens. Which one you choose boils down to personal preference and budget.

Laminates are waterproof, microweaves are not.

Microweaves are generally cooler than laminated fabrics.

Laminated fabrics usually cost less.

Both fabrics require special care when washing. You can’t use high temperatures or chlorine bleach on laminates. Microweaves need gentle agitation to protect the weave.

Are Dust Mites Sleeping With Your Kids?

I heard on the news that the Transportation Safety Administration (TSA) is changing their guidelines for pat downs for young children.  Seems there was quite a bit of uproar and outrage by parents.  They didn’t like strangers touching their children.  Didn’t think it was safe.  I don’t blame them. I wouldn’t want strangers touching my kids either (and they are both grown!)  But are dust mites touching your kids?  Are dust mites sleeping with your kids every night?

I chuckled to myself  and wondered, exactly how many of those parents who were so outraged gave any real thought to what was in their kids beds.  “No Mr TSA, you may not touch my child. But when we get home I am going to let her go to bed with 10,000 dust mites”  “Ms TSA, you may not touch my baby boy because it is dangerous, but at Grandma’s house I am going to let him sleep on a mattress that has been treated with all sorts of toxic chemicals.”

I would venture a guess that the child is more likely to suffer ill effects from the dust mites or the chemical fire retardants in their mattresses than their brief encounter with a TSA agent.  But you can see the TSA agent, the danger is visible.  Those nasty dust mites are microscopic and you can’t see or feel them, but they are there.  Their dead body parts and feces just awaiting to cause problems with allergies, asthma, or eczema.  The chemicals used to treat mattresses are also invisible.  If you have a sensitive nose, you might be able to smell them if the mattress is new.  But, they are still there, waiting to cause respiratory problems and worse.  Some of the fire-retarding chemicals are suspected to cause cancer.  Those threats are more real than the TSA, but dust mites sleeping with your kids seems less of a threat because you can’t see dust mites.

Have you ever moved an old mattress?  Gosh!  They are heavy aren’t they!  That is the combined weight of all of those years worth of dust mite bodies, feces, and your skin.  If you haven’t lifted a new mattress lately, you will be surprised. They are light.  That is because they have limited numbers of those nasty critters in residence.

Those are the same nasty critters in your child’s bed.

Doesn’t it make sense to protect your child?  You can use a urethane-lined allergy proof mattress cover to protect against dust mites.  The lining will make the cover waterproof as well as trapping in fumes from flame retardants and other chemicals.  If you don’t want the urethane lining, a microweave dust mite proof cover will keep the critters at bay.

You may also give some thought to organic mattresses.  Yes, they cost more to purchase, but what price is peace of mind?  There are several manufacturer making quality products and the price just might surprise you. Natura and Pure-Rest both make organic mattresses.  Just something to think about, when standing in line at the airport….waiting for Mr or Ms TSA.

Allergy Mattress Covers and Mattress Covers Are Different

There are mattress covers and then there are allergy mattress covers . What is the difference?

A mattress cover is designed to protect the mattress from spills, soil, sweat and the oils from your skin that can come through the sheets.  The regular mattress cover is on the bed to protect the mattress from you.

The allergy mattress cover is on the bed to protect you from all the allergens that collect in your mattress.

The traditional mattress cover may be made of cotton or some sort of cotton blend. Some are zippered and others fitted. Sometimes, people will even put a vinyl cover on the mattress to give water-proof protection.  Great for the mattress, not so great for the person trying to sleep on the mattress. Vinyl makes noise when the you move move or shifts and because water vapor can build up under the cover it makes for very hot  sleeping. Read rest of article on allergy mattress covers.
