## Description

3M Respirator Half Mask Lightweight Blu : desertcart.co.uk: DIY & Tools

Review: ITS A WONDER - I look a bit like Darth Vadar and scare the kids , but who cares this does the job. Wearing glasses I find that a lot of masks steam them up due to exhaled breath escaping upwards onto the lenses. A nuisance and often dangerous as many tasks require good clear vision. The exhale , one way escape valve solves this very real problem. I have now used it for several tasks generating dust and microbes e.g. sanding plasterwork and strimming grass. The 3M mask protected my nose and mouth preventing anything entering my breathing system. As an acute Hay Fever sufferer many garden tasks were a problem inducing streaming eyes, streaming nose and persistent cough. Since getting the mask I have cut and strimmed grass, power cut a hedge and so far no symptoms . After a few adjustments it fastened securely with 2 straps ; the rubber seal is snug , but not painful , it does not constrict breathing and most of all it filters all the bad stuff. Can't believe the low cost for such a quality protection. PS having used it for a few weeks the elastic bindings constantly slip from the buckles so have had to tie knots to secure them. Not a big problem more a nuisance
Review: efficient - and surprisingly comfortable - i bought this mask last week: i'm surprised at how efficient - and surprisingly comfortable - it is. i'm wearing it in dusty situations, and it seems to work really well. if you're a claustrophobe you might find it a little disturbing to start with - but you soon get used to it, once you've found you can actually breathe! a tip for spectacles wearers: put the mask on first, then your specs, otherwise you can get the lenses marked as you pull the mask onto your face. update: it's a really good mask - i've been using it to filter dust from cat litter - but after a while it gets harder and harder to breathe through it: presumably it's become clogged, though you can't tell that from looking at it. as i've only had it a month or two, this makes it quite an expensive mask. however, it certainly does the job. second update: this will be my fourth buy, to date. i find the masks last at least a year, if you give them a once-over with a vacuum cleaner nozzle from time to time. excellent for keeping out dust from cat litter, if you're asthmatic. the fit round the nose is very good. third update: i've now had five of theses masks. my only criticism of them is that the filters are non-replaceable. otherwise, they're good quality, comfortable and seal well - and keep out dust.

## Questions & Answers

**Q: Does it double up as a jock strap?**
A: I think it best you seek medical advice if your jockstrap region is giving off organic vapours and particulates dangerous to health.

**Q: Will it steam up my glasses**
A: Condensation from a mask is due to poor ventilation, which cheap paper masks are prone to creating since they have a really basic valve, from using this I found it stays quite cool on your face as it brings in cool air with each breath and exhales hot air brilliantly too. I wear plastic safely glasses when using this and from my experience I havnt had them fog up. I suppose its thanks to the valve on the front that sends the hot air out in a jet rather than letting the air rise upwards which is a common prob with cheap masks. Hope this helps

**Q: is it easy to buy new filters for the mask**
A: Trying to remove filters is extremely difficult. I keep mask for year and then discard. Seems OK providing you use with close fit. If its just for paint and you can't smell any odour its probably working OK. Trying to get more info from makers is really difficult.

**Q: Would this product be suitable protection from airbourne mould spores, for use when cleaning mould from a property?**
A: Probably adequate but it would be better to use the 3M 4255 respirator which gives protection up to P3 level this includes high levels of mould (See  HSE Guidance, Industries - Agriculture, Articles 'All you need to know about disposable dust masks').

### ⭐⭐⭐⭐ A good value upgrade from disposable masks, you will wonder how you ever did without one...
*by J***Y on 27 April 2016*

Really great product. I got fed up with having a sore throat and nose from dust etc when wood working and restoration jobs so decided to get a decent mask. Does a great job with dust exclusion and also keeps out the majority of fumes, you still get a sight wiff but its OK. Fits snugly around nose and mouth. Straps very securely around head and is very comfortable overall! I wouldn't even notice I was wearing it... Except for one thing... If you wear the mask for any length of time, your breath starts to condense inside it and you get a drip of water at the end of your nose! And I don't know about you, but a drip at the end of my nose is impossible to ignore, so I have to take it off and sort it out! So this is a bit of an annoying flaw, but unless you want to fork out for a sophisticated respirator, you will just have to live with it! Makes you realise how crappy and useless disposable masks are! Overall a very good mask for the price!
