Distilled water

You still need to get rid of the dissolved oxygen.

If you boil this water almost all oxygen is out.

This is the .99 cent distilled water i get from my local grocery store.. It states Purified by steam distillation, filtered and ozonated.

This water is ordinary water which is boiled to create steam. The steam is condensed into another container. It is then filtered to remove particles and Ozone is bubbled through it to kill bacteria and mold. The ozone dissipates quickly and is gone by the time you use it.

Here distilled and deionized water must be respectively labeled in a distinct manner. I use only real
distilled for unusually fussy or pH-sensitive work like matched separation negatives, as well as for
final rinse of negatives with Photoflo. But our tap water here is so good that I use it for anything
routine, including conventional black and white developers. Stored concentrates are always mixed
up with distilled, however, just in case. Our city water is largely snowmelt piped in directly from the
Sierras. But there are plenty of other places in the state where either the mineral or chlorine content would make it unusable in the darkroom.

My water here in the east bay area of San Francisco is very soft and considered excellent water. Nonetheless I use distilled for developing as I often my negs are "dusty" even when there is no dust to be seen on the neg surfaces. Using distilled my negs are much cleaner.

Paper coffee filter inside a plastic funnel. My 'free' distilled water was clean apart from a couple if fibres the filter held back.

I chose a condensing dryer because where it is situated there is no access to the outside. It is actually in the garage near to the kitchen door so it is convenient that way too.

All the lint that comes off the clothes that are dried are caught by a fine mesh gauze 'skin' so no fibres actually get through to the residue water.

Dryer condense is more like a solar distiller, not really a distiller by the book but obviously good enough for darkroom purposes in Your case.

The condensed water from a drier will be contaminated with bacteria and mold spores (as well as the lints and other particles) the last thing you want to have in water you use in photography whether for making up solutions or washing and rinsing.

Cheapest solution in the UK is a de-ionising water filter the Brita type (or equivalent) are inexpensive and in every supermarket. Buying water distilled or de-ionised is expensvive in the UK unless you buy in bulk.

a de-ionising water filter the Brita type

Indeed one of the best solutions and when boiled almost oxygen free.
