Get a mattress encasement, it's like a HEPA filter bag for the mattress (cuts off the mites food supply and preventing allergens becoming airborne).

Skips the whole trying to clean porous foam problem.



I read that mites can't survive temperatures above 60C, and wondered then about just a big plastic bag around the item then fill it from a hot air source (hair dryer, fan heater)?

I think the problem would be temperature control, as you don't want to damage the item, but need to maintain an even, specific air temperature, you'd need turbulence. Then vacuum clean afterwards.

Maybe a wallpaper remover style device with a hot air source instead of steam??


Yeh I've thought about whether it'd be possible/safe to use something like an "overclocked" electric blanket to sterilize the mattress daily.

They also need humidity (~50% RH), hence why I got the dehumidifer, which has definitely knocked them back.


I got the exact same idea sadly most electric blanket i could find on amazon where kinda small and had disappointingly low heating power...


Pretty much my conclusion as-well.

I guess they just don't want folks giving themselves burns during sleep.

AliExpress as always is tempting [1], but you'd have to be incredibly careful about regulating temperature [2] and adding safety interlocks that'd make falling asleep with it active, or forgetting to turn it off impossible.

Look into something like flexwatt tape. Maybe run it during the day when your not sleeping. In my mind, they probably use something similar inside heated blankets with some kind of limiter/thermostat.

Do your research though!! I'm not sure if flexwatt tape could ignite your mattress, but you would definitely want to know for sure yourself beforehand!

There are ways to control heat though; I'm familiar with using flexwatt tape with reptile enclosures, hooked up to a thermostat with a probe in the habitat for temp control. Maybe some math, like desired_temp = watts_supplied * feet_of_fw_tape, where the watts_supplied is the independent variable you adjust based on the required feet_of_fw_tape for your mattress to get the dependent variable desired_temp. Probably include a fail safe, but I'm no electrician, proceed at your own risk.

They do sell self contained fire extinguishers you can hang on your ceiling that deploy automatically at a certain temperature, ideally putting out fire sources they are hung above. Nice to have around for things like this.


nice another project to the pile ;p

People do something similar to kill bedbugs, I think they make specialized equipment to do so, but it might just be something like an off the shelf heat gun.


Just a data point. I have a mattress encasement which has never been removed (I got it to protect against bedbugs). Dust (dead human skin) still accumulates on the surface. It might not go into the mattress, but it will be on the surface. Since the encasements are never meant to be removed, vacuuming the mattress (with encasement on) still makes sense.


I asked above as well, but since you have direct experience, what do you have between the plastic and you? Aside from the fitted sheet? Wouldn’t a regular mattress cover just attract mites as well?


It’s just the fitted sheet.

The encasement I have is actually not a plastic wrap but a zippered tight weave synthetic fabric (polyester).

It’s suppose to prevent bedbugs and others from setting up shop inside the mattress but the surface is fair game. The idea being it’s easier to clean the surface than the insides.

I have had the encasement for years. No problems with humidity but I also live in a less humid area (41-45% rh all year round).

So a dust mite vaccuum still makes sense.

Also interesting fact: dust mites themselves are harmless to humans. It’s their fecal matter (after digesting our dead skin) that are allergens.


Ok. What do you put between the plastic and the sheets? A standard mattress cover? Won’t the mites just go there as that’s where the dead skin, etc will be?

The plastic would also trap heat between me and it.


As someone who uses a plastic mattress cover I can answer your question: yes, if you let dust build up, mites can and do start to live on the fitted sheet that you put around the mattress cover. However, it is of course easier to wash just the fitted sheet than to remove dust from within a mattress, so I think that a cover is still beneficial.

I'm not sure what you mean by trapping heat - once there are two normal cotton fitted sheets around it, I don't feel the plastic mattress cover at all.


This causes mold by trapping humidity. Had to throw out a latex mattress be careful with full plastic.
