About MiteGuard dust mite allergy bedding covers

MiteGuard makes dust mite barrier bedding covers in New Zealand, born from one family's own struggle with allergy symptoms and thirty years of science behind every cover we make. If you're lying awake next to a wheeze, a stuffy nose, or eczema that flares every night, we've been exactly where you are — and we built something to change it.

Why we started MiteGuard

We're a family-owned company, and MiteGuard didn't start as a business plan — it started with our own family losing sleep to dust mite allergy. Coughing, sneezing, itchy eyes at bedtime, eczema that wouldn't settle: if any of that sounds familiar, you already know how much one bad night can cost a whole household the next day.

Today we make MiteGuard and AllerProtect covers — 100% natural cotton mattress, duvet and pillow covers built to block dust mite allergen — because we wanted the product we couldn't find ourselves. Every cover is made by Kiwis, for conditions we know first-hand, backed by real customer service from people who understand why this matters.

Who founded MiteGuard, and why?

MiteGuard's story goes back to 1994 and Richard Thorogood, a New Zealand microbiologist working in the School of Biological Sciences at the University of Auckland. Richard's conviction was simple: better science should mean better lives for allergy sufferers, not just a diagnosis and a list of things to avoid.

Why did Richard focus on dust mites specifically?

Dust mites thrive in New Zealand's temperate climate, and our older housing stock — often poorly insulated and damp — gives them ideal conditions. They live in soft furnishings and love beds most of all, because a sleeping body provides exactly the warmth and moisture they need.

Your mattress and pillow are usually the biggest reservoir of dust mites and their allergen in the whole house — a single mattress can hold an estimated 2 million dust mites — and you spend roughly a third of your life in direct contact with it. That's why Richard focused his research there first: a barrier cover on the mattress and pillow addresses the single largest source of exposure in the home.

How did the first MiteGuard cover come about?

Richard wanted an alternative to the heavy, hospital-grade vinyl covers that were the only option at the time. After following a 1990 Lancet⁽¹⁾ article on new allergy fabrics developed in the UK, he made the first MiteGuard covers in 1994 through his own company, Allergen Services Limited.

Thirty years on, materials technology has let us refine the fabric and construction, but the commitment hasn't moved: every decision is grounded in research, and every cover is made to genuinely help the person sleeping under it. We still work with the same trusted New Zealand manufacturing partners, and remain a market leader in scientifically backed allergy barrier bedding.

Why families choose MiteGuard

Restless nights. Blocked noses. Wheezy breathing. Itchy skin. A whole family running on not enough sleep. If that sounds familiar, dust mite allergy is very often the hidden cause — exhausting to live with, and hard to explain to people who haven't dealt with it.

The good news: something as simple as the right bedding cover can make a real difference. Encasing your mattress and pillows in a genuine dust mite barrier fabric cuts exposure to one of the most common allergy triggers in the home — for many families, that means fewer symptoms, better sleep, and a bit more breathing room for everyone.

We know living with allergies, eczema or asthma doesn't just affect the person with the diagnosis — it affects the whole household. That's part of why we work alongside organisations like Allergy New Zealand and Asthma New Zealand, who support Kiwi families navigating exactly this.

MiteGuard is a proudly New Zealand business, and every cover supports local workers and local manufacturing. Whether you're just starting to look into dust mite allergy or you've been managing it for years, we're here to help you find the right fit for your home.

Certified New Zealand Made — what that actually means

Plenty of brands say "Made in New Zealand." We're licensed to say it, and that's a meaningful difference: it's a legal claim we have to earn and keep earning, not just a phrase on a label.

What does the Kiwi trademark actually certify?

The Kiwi trademark on our covers is issued by Buy New Zealand Made, the campaign administered by BusinessNZ, and the claim it represents is tied to the Fair Trading Act. To hold the licence, a manufacturer has to prove that a product's essential characteristics — the qualities that actually make it what it is — come into being here in New Zealand.

For a woven cotton cover like ours, that means the precision microweave fabric is cut and sewn into the finished allergen barrier cover on New Zealand soil, under New Zealand oversight. Raw cotton fibre can be imported where it isn't available locally, but the process that turns it into a MiteGuard cover has to happen here.

How long has this certification scheme existed?

It's not a new or casual mark. The current Kiwi trademark licensing scheme dates back to 1988, with roots in New Zealand Industries Week, first held in 1908. When you see it on a MiteGuard cover, it's the same standard New Zealand manufacturers have been held to for decades — not something we designed ourselves.

How do I know if I have a dust mite allergy?

Allergies are usually medically diagnosed and can be complex, but common signs of dust mite allergy include coughing and sneezing at night, a stuffy nose, or eczema and asthma symptoms that worsen after time in bed. Read more about dust mites and dust mite allergen.

We think that kind of accountability matters for something your family sleeps under every night. Below is our current Certificate of Licence alongside the Kiwi trademark itself, so you can see what's actually been verified — not just take our word for it.
