Lifetime Filters Explained:
Many Dysons were marketed with 'lifetime filters'. In my
opinion (and it must be understood this is 'my' opinion for legal reasons)
, this is typical marketing babble that was never properly quantified by Dyson. Who's lifetime? The lifetime of what? (Really, the ASA or trading standards could have had a field day here)
The machines lifetime? (At Manchester Vacs they never die so go figure.....)
The lifetime of the motor?
We typically have two filters on a Dyson. The pre-motor washable filter and the post motor filter (Which might or might not be a HEPA filter).
HEPA filters cannot be washed and still work properly (ignore what those who tell you otherwise say)
. When they are clogged, they are clogged and need replacing. That usually means plaster dust.
Post motor filter pads
can be washed, but often don't survive washing and are cheap enough to replace anyway.
Washable pre motor filters are not usually washed properly by people (following Dyson's instructions)
. They tell you some waffle about rinsing them under the tap. For a badly clogged filter that will be totally ineffective. The filters we refit to machines are cleaned with a steam cleaner (pressure washer) first and then put through a washing machine (which Dyson also does not recommend )
. Ours are like new - most people find it easier to buy a new one.
If the motor has died, you need to replace both filters really. Most after-market motor suppliers will not honour a guarantee on a motor unless proof of filter purchase is supplied also.
So what is a lifetime
filter? Marketing waffle really........ (in my opinion)
If you have used your Dyson for plaster dust, it needs both filters - guaranteed!
If you swapped your motor, it needs both filters replacing. The machine is old enough that the motor dies, so yes, it needs new filters too.
Clean filters stop the motor over heating. Motors that overheat cut out and/or die.
Dyson filters are NOT lifetime
by any definition (in my opinion). That's why people sell them......
