Was dubious about buying, a bag, of the beeswift mp1 gloves, as I was actually looking for an alternate brand, I've had gloves before that were all bundled together, where the rubber was too hard and the material like an old rope, the company sent them out really fast delivery, individually wrapped, premium gloves, really happy, top drawer, as these will be stored in the garage, no damp or spider issues, big thanks to George @ gloves & stuff.

Decent gloves at a reasonable price. Delivered within a good delivery window. These gloves have reasonable longevity in medium workloads.

Good company to buy from; just took a bit longer than expected (9 days)from order to being despatched for delivery. The response was quick when I emailed them with a query. Will definitely use again.

C Cherie Rowdenvia Trustpilot

I've always had a good experience with this family run business, always able to ring and get any queries sorted. Quick delivery and products all as described on the website.
The process from order to delivery is smooth and stress free. I would definitely recommend them.

What an amazing company. I bought safety shoes from them and could not fault them with anything. Communication from the seller was spot on. Kept me updated on delivery times and delivery was super quick as well, not to mention that they had the best price out there. These shoes are so comfy :). Thank you very much, I would happily use them again and highly recommend to anyone. I am glad I did not cancel my order because of the previous bad reviews.

A pleasure to do business with George, Paul and the team. Have been using them for years and will continue to do so. Great customer service, speedy shipping and an extensive range of products.

Ordered some safety trainers as they offered the fastest delivery and lowest price. My order was a day late but this was due to a supply chain issue with the manufacturers. George kept me up to date and they still arrived before other company’s expected delivery date. The quality of the trainers are amazing and I will be definitely using this company again for my future supply’s.

Description

FFP3 Protection With a Drop-Down Design That Actually Makes Sense

When you're working in dusty or hazardous environments, you need a mask that stays put and keeps you protected without driving you mad. The Portwest P311 delivers FFP3-level filtration — the highest class of filtering facepiece — with a minimum 99% filtration efficiency against solid and liquid aerosol particles. It's built for serious environments where you can't afford to cut corners on respiratory protection.

Key Features:
  • Innovative Drop-Down Strap Design: The strap and clip system lets you lower the mask quickly without removing the full harness. Ideal when you're moving between dusty and clean areas throughout a shift.
  • FFP3 Filtration — Minimum 99% Efficiency: The highest protection class available. An Assigned Protection Factor of 20x the WEL, or up to 50x the TLV based on the Nominal Protection Factor. Suitable for fine dusts, fibres, aqueous mists, and oil-based aerosols.
  • High-Performance Exhalation Valve: Significantly reduces heat and moisture build-up inside the mask. Wearing it for a full shift is far more comfortable than a standard unvalved respirator.
  • Dolomite Clogging Tested (D-Rated): The optional Dolomite test confirms this mask holds up in fine dust environments without the filter degrading quickly — giving you reliable protection throughout extended use.
  • 100% Metal-Free Construction: No metal, no nickel, no ferrous materials. That means it's safe to wear near MRI equipment and in environments where metal components are a concern.
  • Internal Foam Nose Gasket: Forms a tight, comfortable seal around the nose bridge — one of the most common weak points in disposable masks. Less leakage, better protection.
  • CE Certified: Certified to EN149:2001+A1:2009 FFP3 NR D, CE-CAT III. That's the standard that matters when someone asks you to prove your PPE is compliant.
  • Pack of 10: Supplied in a pack of 10, making it easy to keep stocks topped up across a site or team.

The Portwest P311 is a well-thought-out FFP3 respirator that solves the everyday frustrations of disposable mask wear — overheating, poor fit, and fiddly straps. Certified to EN149:2001+A1:2009 FFP3 NR D and CE-CAT III, it's the kind of mask you can hand to your team with confidence. Order yours from Glovesnstuff today.
