No pillow is more economical over time than a quality buckwheat hull pillow. There are two primary reasons for this. First, a quality buckwheat pillow costs about the same as a comparable conventional pillow. Secondly, the life of a quality buckwheat pillow is far, far longer than that of a conventional pillow.
The reason for this is not that the buckwheat pillow is actually physically made that much more long lasting, but in the ugly reality of dust mite infestations. Dust mites (You really need to see a picture of these disgusting creatures taken through a microscope) build up by the millions in conventional pillows (Not so in buckwheat hull pillows). They live on dead skin cells that fluff off your face as you sleep.
They can cause all kinds of allergic reactions as well as respiratory ailments and chronic sorts of infections. From a health and hygienic standpoint, it is recommended that a conventional pillow be replaced every six months. There are some manufacturers of conventional pillows as well as mattresses and other bedding, that attempt to solve this problem by treating their products with pesticidal chemicals. This is not an ideal answer to the problem, as the chemicals may prove to be a more serious problem than the dust mite infestation. Buckwheat hulls, on the other hand, do not support dust mites, and the covers are easily washed.
So your choice is very obvious. You can either choose a pillow that really should be replaced every six months, or buy a much more comfortable buckwheat pillow that will provide healthy sleep for at least fifteen years for the same initial cost. You do the math.

Buckwheat hull pillows were in use from two to three thousand years ago, and now they’re making a comeback. The newest technologies in sleeping are the air chamber mattresses where you can dial in your preferred “sleep number” which signifies the firmness you prefer at any given time, and the “memory foam” type mattress which uses your body heat to make the mattress conform to the shape of your body.
