Dyson Filter in Neato?

Postby glnc222 » August 24th, 2013, 10:26 pm

Shown is the Dyson washable HEPA filter in one of their vacuums, along with a Neato filter. The Dyson is a sponge around an inch thick, available under $10 at Amazon http://www.amazon.com/Generic-Washable-Pre-Filter-Assembly-911236-01/dp/B002JAMDG8/ref=sr_1_10?s=appliances&ie=UTF8&qid=1377396359&sr=1-10&keywords=dyson+hepa+filter. Only very fine particles ever reach this filter after intense centrifugal extraction. Supposed to wash every six months in regular use cleaning (for Neatoless persons).

Looks like a piece of this material could be cut out and mounted in a Neato. Two pieces per Dyson it appears. Maybe split thinner, for Neato's lower air flow.

Thing is, this is the only washable HEPA filter I've seen. Specified for lifetime use.
Could be used with tissue paper pre-filters or something in Neato. Lower dust bin capacity a bit.
Opinions?

I ordered just the HEPA filter from Amazon. Will see what effort is required to make a Neato mod.

Coarser than full HEPA fineness. They would tout HEPA if it met the standard.

Doesn't specify washable so probably not. Electrostatic chemicals to wash out and loosely packed fibers to disarrange. These last months if vacuumed every 6 runs or so, and pre-filtered with singly-ply tissue. HEPA's catching more may not last as long.

Washable HEPA's seem to be an innovation of the last few years, unnoticed if you had not recently bought something with them. Dyson has had them a long time.

The problem is my new Allergy Hepa filter after 2-3 month of usage lost his throughput ability, even while I'm cleaning it(the filter) with standard Vacuum. So I decided to wash it yesterday.

Hard to tell what effect washing has on the finer particle filtration important for allergies etc. without industrial equipment. Wait for spring flowers?

[edit] Without details of the premises it is hard to interpret filter life time. Pushing Neato to clean a larger area will wear the filter faster. More frequent cleaning of an area faster than dirt accumulates may not reduce the life time. Places vary in how rapidly dirt accumulates, from the environment and usage of the premises, pets etc. 2-3 mos. use of the Pet & Allergy filter, compared to one month's use of some HEPA filters, isn't out of the ordinary. Some may get 3 mos at a minimum out of the Pet & Allergy, not unreasonable for vacuums. There's no way to replace the filter with centrifugal extraction like a Dyson but washable filters may offer a new solution.

Well .. I got the filters .. hope this works !
Washable Neato Filter may be real nice :)

2 WASHABLE F1 HEPA FILTERS for DIRT DEVIL vacuums

I cut them Open ... and I figure you can make/get 4 neato filters - Per filter :)

I went ahead and made one ..

Used Silicone to hold filter in place .. maybe next time I will use Hot Glue !

Now after making this ..

I bought these awhile back and forgot that I had them LOL
http://www.amazon.com/gp/product/B00B1Z ... UTF8&psc=1
Neato XV-21 Vacuum Cleaner Filter Neato Robotic Pet & Allergy Filter
Replacement For Neato 945-0048 Filter - 4 Pack

And It SURE LOOKS TO ME TO BE MADE OUT OF THE SAME STUFF ..
Filter seems to be made of a plastic material.

So I went ahead and washed one .. and seems to worked just fine!
So Really .. I think Just get a few of these and be happy :)

Dirt Devil material

Air flow through the Dirt Devil HEPA material of the same area as the Pet & Allergy filter is only 67 per cent of Neato's original filter, compared to over 100 per cent for the Pet & Allergy and 95 per cent for an Asian HEPA filter. So it is not the same material. Apparently different grades of that fuzzy coating exist. You might need an electron microscope to see the difference. The extra HEPA grade fineness appears to take more air pressure to use fully, though Neato filters work down to much lower flows. There just may not be much room for any pre-filtering with this.

It is difficult to cut the Dirt Devil filter from its plastic container. Utility knives and scissors don't cut, and wire cutters or sawing is needed (yet once removed, scissors cut single layers of the material easily). It is difficult to glue fan folded material onto a Neato frame without some sort of cardboard form or something to hold the material in place, not sure what it would be. Silicon sealer glue is hard to apply precisely. Altogether messy, for me anyway.

Given the short life found for the Asian filter, a washable filter could be of interest to those wanting the full HEPA standard of filtration. The Neato filter has gotten so cheap not sure it matters much anymore for that one.

[edit] Incidentally washing (with plain water) the Pet & Allergy filter increases air flow more than vacuuming it. Vacuuming increased from 34 per cent after much use to 49 per cent, but washing increased to 79 per cent (of the original Neato filter new; "Electronic Filter Monitoring" http://www.robotreviews.com.hat/viewtopic.php?f=20&t=15981. Effect on the filter's fineness quality unknown. Adding detergents might leave some residue in the filter so is avoided, especially for HEPA filters; also much more work mixing etc.

Recent experiments with other material shows this Dirt Devil might work if refolded into double length pleats for larger area increasing air flow. None available to test at the moment. Its higher density would modulate the air flow keeping fan power within proper limits for good run time, while the higher area would increase dirt capacity -- with washable and HEPA grade properties.
Optimal design of Neato filters is more complicated than appears at first glance. Several factors are balanced in optimum combination.
