Help & FAQ

Protectors vs bedding: what is the difference?

They are two different layers and most people use both.

  • Protectors are sealed encasements with a full zip. They go directly onto your mattress, pillows and duvet and trap dust mites inside. This is the layer that does the blocking, and it is the first thing to buy.
  • Bedding (fitted sheet, duvet cover, pillowcases) goes on top of the protectors. It is the layer you feel, and it is woven so allergens do not build up in it.

If you only buy one thing, buy the protectors.

Do I need to clean or prepare my mattress first?

No. Fit the protector straight onto the mattress as it is. Once it is sealed, anything inside is trapped and cannot reach you.

Can I keep using my own bedding on top?

Yes. Most customers keep their own sheets and duvet cover over the protectors. The protectors do the work underneath.

How do I wash and care for everything?

  • Bedding: wash weekly at 60 degrees.
  • Protectors: wash or vacuum monthly.
  • Do not tumble dry.
  • Do not spin dry the protectors.
  • Line dry or dry flat.

What about items that cannot go in at 60 degrees?

For delicate items that will not take a hot wash, freezing or soaking is the alternative. Call us on 0330 122 1646 and we will talk you through it for your specific item.

How fast will I see results?

Customers commonly tell us they notice a difference within the first week, and some within the first night. Everyone is different, and it depends on how much of the bedroom you have treated. Sealing the mattress, pillows and duvet together gives the biggest change.

What size do I need?

Every size we make, including deep mattresses, small double, cot bed and EU sizes, is listed on our Size Guide. If you are between sizes, go up a size. If you are unsure, call 0330 122 1646.

VAT relief: can I save 20%?

If you live in the UK and you are chronically sick or disabled, including chronic dust mite allergy, asthma or eczema, UK law lets us supply certain items with the 20% VAT removed. On a £300 order that is £250.00 to pay.

  • Eligible: dust mite mattress, pillow and duvet protectors, protector sets and full encasement sets.
  • Not eligible: air purifiers, dehumidifiers, vacuums, sprays and general bedding. HMRC only allows relief on goods designed solely for use by disabled people.
  • No medical evidence is needed, just a truthful self declaration.

Email us the details and we will send you a draft order to pay with the VAT removed. Everything you need is on the VAT Relief page.

Can I pay in instalments?

Yes. Klarna and Shop Pay are both available at checkout, subject to their own approval and eligibility checks. Choose them as your payment method on the payment step.
