so you'd be surprised to know from
one single roll you get 80 80 squares because you get four squares per meter square
good morning everyone brian here again from the london craftsman and welcome back and in today's
video i'm going to be showing you a few tips and well some cheap ways of making some filters
for your spray fans so as you can see here i've got two 400ml fans if i just take a filter off
all they are is a square flat fan a hole in my stud wall with the air just spin
just taken straight out it's simply a hole in the stud wall and a frame all the way around
50 mil deep planned to the same size as my filters so today's video is showing you
how i actually make these filters the cheapest way and
yeah hopefully save you a little bit money i've tried a few different filters and a few
different ways but this way seems to work really well so if you want to make your own filters
and basically make a good handful of them spending 20 minutes yourself you'll have enough filters
possibly for the year with one single roll so stay tuned watch to the end and i hope you enjoy
okay so i've come in the workshop because my filters have been in the workshop
on a shelf and they probably got a tiny bit of dust on them so as you can see
i've got my um filters the remaining ones left in between my two templates there you go that is
the size and you know what i was talking about i actually got more than i thought you see they come
up like a little jack-in-the-box and i shouldn't have done that but i need the templates you can
see why i've got them within my two templates yeah look look how wide they go this is the materiel
this is it
and all it is is the 20 meter roll
by one meter and you you're getting the gist now aren't you so you can cut it any
size you want so basically it should work with any fans that you have up to around
450 because you want to leave space you might get you might be able to cut that dead in half um i
can't remember what i've done let's get a tape measure and measure how wide these actually are
look at that always on the ball shawn is they're 490 so i have actually just made it so this is why
i've got overhang over my my actual fans the frame is slightly bigger than my fans i've planned it so
i cut that dead in half and there's no trimming up to do basically so there we go let's cut it up
and take it out
and just be aware that as soon as you've taken out it probably want to sort of puff up on you
so there we go i've got my little con uh my little um
cutting board underneath yeah you can see actually hit the uh
the tripod it rolled out so basically i'm just lining them up
there we go and they don't have to be critically exact because they'll wedge into your fan
and plus when you have your fan on um the fan you before you try and attach your filters you
want to turn your fan on because you don't then have to tuck them in when the fans on
they just suck straight into your frame so there we go so we've got one set there
so if i just turn that around can then cut this
yeah so that'll be one and then i've got a little bit of excess on that one
simple as you just use a nice sharp stanley blade don't worry they look quite thin at the moment but
they do puff out a little bit more then we got two filters like i said i thought they were actually
square but i've made my my framework apparently it's been two years 520 by 490 around my actual
fan you can make your frame whatever you want just remember that your roll is one meter wide
so you realistically if you want to cut that dead in half you get 500 to 500 don't you or
250 centimeters so you can make your frame there and you can make it probably 50 higher as well so
i have made two of these remember so once i have finished with them
and i want to store them i get all of them in there and then like it's a two-man job believe
it or not compress them one person holds them and one person gets some handy wrap
which is this plastic stuff here and we just wrap them up like so yeah
to store them away and that holds them one there one across here and that holds them just nice and
when i want to pull one out i can literally just grab one and pull it out without ruining the pile
so there we go that is all you really need to know really apart from the links they'll be in the
description um just grab yourself a nice stanley blade a nice board to cut on two templates made
up of whatever you want i've got nine mil osb you can use six mil mdf whatever you have lying around
you get your 20mm roll your two fans 20 meter roll your two fans and away you go i actually thought
i had about six left but i've got about 20. in theory i didn't need to buy another pack but
at least i've got probably another three years worth or i can use them a bit more um i could
just replace them a bit more and just chuck one away a bit more often so i've actually been a
bit of a numpty just had a little thought because i've been looking at my pile and we actually get
40 in length because they're half a meter so it's 40 in length by two so yeah we've been we've used
60 now because there's 20 left so you actually get 80 filters in a roll which is incredible value
for something that's only 50 pounds so i wanted to add that bit because my maths was diabolical
right guys so all cut up ready to be used and i miscalculated how many i had left over had
about 20 left over um from before and i also miscalculated how many i get from a roll so
you'd be surprised to know from one single roll you get 80. 80 squares because you get
four squares per meter square so here we go 20 left over and i just cut 80 up so there's about
100 and something here and this is well over a year's worth of use for me um all depending on how
many times i throw them away and how many times i replace or if i just rip bits off
um it's so cheap i can literally just replace a set every half a job easily so don't delay guys
snap yourself up a roll look at the link stop wasting time and money
um buying singles especially as you can cut them to your own size and to your own
to your own fans that you actually want to buy the sizes that you want to go for
and yeah happy spraying i hope that helps if it does leave some comments like and subscribe if
you can share the video be absolutely amazing guys and i will see you in the next one ciao for now
