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.

Primaloft is the Superior Down-Alternative Comforter

If you have allergies and you love down, your bedding choices have down bedding contributed to allergiesbeen a bit of a downer.  Face it, most materials that have been manufactured to be an alternative to down are just down-right awful. They clump, they lump, they just aren’t down.  That’s until Primaloft perfected the down-alternative and created a down-alternative comforter that feels just like down!

Air is Nature’s Insulator

Down is a made up of the feathers from various birds.  The feathers form little balls that trap air.  Down is such a comfy filling for a comforter because feathers don’t weigh much and the air they trap doesn’t weigh much.  However, air is a great insulator.  Its what makes down and wool warm.  But unlike wool, down doesn’t weigh much.  So, you get warmth without much weight.

The Problem with Down Comforters

Down comforters are warm and provide a comforting weight.  However, the feathers inside are magnets for dust mites.  Unlike wool, which has lanolin, down doesn’t have any natural property to repel dust mites.

Some people are actually allergic to the feathers themselves, but this is not as common as allergy to the dust mites they harbor.

Another negative to down is keeping them clean.  Most down comforters are destroyed by washing and drying.  The fill clumps and lumps and feathers poke through the cover.  It’s a mess.

Primaloft is the Down-Alternative Solution

Finally, down lovers have a solution – Primaloft.  The patented Primaloft fill is a synthetic fiber with all the good properties of down and none of the bad.   In addition, Primaloft can be safely washed and dried over and over again.  Hotels and resorts have used Primaloft fill for luxury bedding for years.  Now it is available for home use through The Allergy Store.

Primaloft Down-Alternative Comforters

Down Alternative Comforter

Primaloft Down Alternative Comforters are the perfect alternative to down.   Each comforter is filled with Primaloft fill treated with an antimicrobial to prevent the growth of molds and bacteria.   They are covered in a silky smooth 230 thread count Cambric cotton fabric that feels simply silky against your face as you cuddle in comfort.

When its time to freshen your down-alternative comforter up, there are no worries and no fuss.  Just pop in the washer and dry in the dryer.  No expensive dry cleaning process is needed.

Treat Your Loved Ones – Treat Yourself

Bed Bugs are the Real Vampires

When I was a kid, the old black and white movies with scary monsters like vampires and mummies were some of my favorites. As I got older, I loved movies (like Young Frankenstein and The Rocky Horror Picture Show) that allowed me to laugh at my fears.

Currently zombies fill the screens of horror flicks. Zombies are scary, but what really frightens me are the thought of real blood-sucking creatures crawling into bed with me at night. I’m afraid of bed bugs and I have never been bitten by one. Yet.

Bed Bug PTSD

I went looking to see if the fear of bed bugs had been given a specific “phobia” name. I didn’t find a phobia for bed bugs in particular. The fear of beds is Clinophobia and the fear of bugs is Entomophobia, but there isn’t a Clino-Entomo-phobia as of yet. Give it time.

I did find that people who have actually had a bout with bed bugs may suffer from an anxiety similar to mine known as “Bed Bug PTSD”. I am not making this up. The Atlantic published an article about bed bug anxiety . Well, OK, they called it “madness” but even I think that is extreme.

Bed Bugs Keep You Up Last Night?

Turns out that once you survive an infestation of bed bugs, the expensive and time consuming eradication process can leave you emotionally scarred. I believe it. I’ve never had bed bugs, but I have helped so many people going through the bed bug extermination process that I live in fear of bed bugs.

Bed Bugs are Evil Blood Suckers

EHSO has some pretty good information about bed bugs. In a bed bug photonutshell, these bugs are small, but are large enough to be seen with the naked eye (unlike microscopic dust mites). They feed on blood. Human blood in general and your blood in particular is their favorite meal. They use two tubes, one to inject an anticoagulant and another to extract your blood. They feed every 5 to 7 days and they are attracted by the carbon dioxide you exhale.   I guess you could just never exhale. Let me know how that works for you. The anticoagulant they inject causes a bump and an itching sensation.

The little buggers will hide anywhere, but close to you and your bed is one of their favorite locations. For many years they were considered to be pests of the unclean. But as we travel more and the world gets smaller, bed bugs can be found in the finest homes and hotels and the most modest motel and slums as well. No place is immune.

Now Recognized as a Health Risk

For years bed bugs were considered a disgusting nuisance but not a carrier of disease. People were found to be allergic to the bites, but that didn’t pose any more health risk than allergy to mosquito bites or other insects. However, recent research has shown that bed bugs can be a carrier of Chagas Disease. So fear of bed bugs isn’t completely irrational.

Calm Your Bed Bug Fears

Having confessed to my bed bug fears, here are some things I do to prevent a bed bug infestation from ever happening to me. It has been successful so far, but I am sure as soon as this gets published I will get bed bugs. Like punishment for bragging. So here is my routine:

Bed Bug Covers. My mattress and pillows are all protected in zippered bed bug coverszippered bed bug proof covers. I am highly allergic to dust mites, so I need zippered covers for dust mite protection. I use the AllergyCare Linen bed bug proof and dust mite proof fabric so I literally kill two bird (or is it bugs) with one stone.

Bed Bug Avoidance. Since I don’t have bed bugs in my house, I don’t want to bring them into my house. So, when I travel my suitcase stays in the bathtub at a hotel. I never put luggage on the floor.

When I come home, my suitcase stays in the garage until it can be thoroughly inspected and the clothing goes from the garage into the washing machine before it ever comes in the house. If you want to know in detail what I do to avoid bed bugs when I travel, you can read this related post from 2012. See, I have been afraid of bed bugs for years.

Bed Bugs are Scary

So yes, bed bugs are scary. They don’t fly like vampire bats; but I haven’t read a case of someone picking up a suitcase full of vampire bats by staying in a hotel. I read about bed bugs in stores, but I don’t read about vampire bats in stores. You get the idea.

In reality, bed bugs are to be feared more than vampires. In fiction, bed bug zombies would be the worst!
