    Cottonfresh natural cotton fabric is certified by Oeko-Tex standard 100 and carries the Confidence in Textiles trademark, guaranteeing the fabric is free of harmful chemicals and 21 specific allergens. Oeko-Tex standard 100 is a European global testing and certification system for screening harmful substances in consumer textile products. It sets stricter limits than current EC legislation on banned or restricted use substances used in textile manufacturing.

If you wake up in the morning with itchy, watery eyes, nasal stuffiness, runny nose, and in some cases asthma you may be allergic to dust mites and their allergens. These allergic reactions to mite allergens can be a year round problem. Dust mites live in mattresses, comforters, carpeting and upholstery. These Cottonfresh dust mite covers provide a barrier against 99.95% of dust mites and their allergens. Since we spend almost one third of our lives in our bedroom it makes sense to make it a healthy enjoyable place to be. One of the easiest, most economical solutions is to encase your mattress and pillows with zippered, tightly woven dust mite covers. Put your sheets and pillowcases over these covers.

These dust mite covers are closed by a fine zip fastener and may be washed at high temperature. The manufacturer recommends laundering them every few months month if used under standard sheets and comforter covers. Wash pillow covers once a month. The cloth is pre-shrunk but there may be an additional 2% shrinkage if washed at high temperatures. This extra shrinkage actually makes the weave tighter still and therefore more protective.
It is constructed of 100 percent unbleached, undyed and untreated all natural cotton, which has been tightly woven and specially finished for unique allergen barrier properties. The only treatment applied to the fabric after weaving is washing with a washing agent to remove impurities picked up in the weaving processing followed by rinsing in water. No other substances have been applied to the fabric.

  • Small pore size of 3.45 microns is very impressive for a woven natural cotton dust mite cover and will efficiently block dust mites and their allergens
  • Fabric is a lightweight cotton with a soft sateen feel. You will not even know these are on your bed or pillows.
  • Fabric is made from a pure natural cotton that is Eco-Tex(Oeko-Tex) certified guaranteeing it to be free of harmful chemicals and 21 specific allergens that are commonly used in manufacturing textiles
  • Safe for those with sensitive skin or Multiple Chemical Sensitivities
  • Very impressive fabric and construction quality


  • As with all woven dust mite covers, these will reduce in efficiency over time as wear and repeated washing will naturally increase the pore size of the fabric. Wash only when necessary to extend the life of these covers.


Cottonfresh represents the latest developments in allergy avoidance bedding. Barrier covers for pillows, duvets and mattresses have been around for a while now, but usually relying on synthetic fabrics and plastic membranes to keep house dust mite allergens at bay. But these materials can be unsuitable for anyone sensitive to chemicals or who find synthetics hot or noisy to sleep on. Cottonfresh are soft, smooth and feel more comfortable than even regular cotton pillow case covers. We heard about a UK firm which has made a major breakthrough in quality and comfort with their Cottonfresh dust mite covers and tracked them down. We had samples of their barrier covers sent over to test for our members and believe me they are the 'Rolls Royce' of allergy free bedding! Cottonfresh barrier covers are made of 100% pure natural unbleached cotton. The Cottonfresh fabric has been tested and found to have a pore size of 3.45 microns which is well below the 10 microns needed to block dust mites.
