Alternate for Yama Cloth Filters

I just took some canvas cloth, cut it to fit over the metal holder, sewed it in place and it lasts for months and  months.

Very glad to have found these filters. I had been using one filter on my Shark Rocket for a very long time, washing it often. So it's a relief to have spare filters on hand for quick changes.

These are more expensive than the style i was using. However, the old style used a couple of combs that need to be placed spacing the filter apart. It was a pain. I can change these in a couple of minutes with no fuse and put the old dirty one in the box that held the new filter. Worth the price with less mess and hassle.

It is difficult to find the hollow circular filter pad for this filter, but Amazon has it. Even though it is expensive by counting on material itself, but it is still cheaper to order from Amazon than any other places.

I wanted the filters that would fit the lovely little stainless steel Natural Home compost container that I bought last year at the Mother Earth News Fair in Seven Springs. Imagine my surprise at finding them here at Amazon. Yes, they are a tad bit more expensive than the cheaper ones you can get and cut to size, but why bother? I thought the price difference vs. the time I would spend (or keep forgetting or putting off doing) trimming the new filters wasn't worth it. For me, I'd rather spend every last minute out in my garden or something else that keeps me occupied. I dislike busy work.

I buy a lot of replacement filters for all of our family vacuum cleaners. These were the best value for two separate filters. The replacement filters all seem to look alike upon arrival. The quality issue comes into play once the filters are being washed to be reused. I have not had to wash them yet so if there is a problem, I will edit this review. Cheap price. fast delivery. I will buy from this seller again.

Unfortunately there are not too many alternatives. It's great to have the scrubbing/lathering sides, but too often the later side starts falling apart too soon. Tried the Dove one as well, same problem. Seems like they are designed to fall apart easily.

There are plenty filter adapters for most of the popular sizes.
The kit comes with so many filters that I had to leave half at home because carrying all the filters would take up too much space in my bag.  Great value.

Good filters.  Didn't fit my model shop vac though, they were short so I had to jerry rig them in

I ordered these filters because Amazon was so much cheaper than other sites.
When I wen to replace my filter I discovered how filthy my old filter had become. I plan to replace them regularly.

I normally buy packs of 3M filters, but in the last year the price has almost doubled. Why? So I am looking for an alternative at a good price and trying these. The merv rating isn't as high, but sufficient and better than real cheapies. Plus they are pleated for more surface area. Sometimes I think the super high mervs are not allowing enough air passage. May be my imagination. I am on the first of these filters and no complaints. Try them.

Works with the lens and the filter, microfiber cleaning cloth is very good. The tread is smooth and it is metal

I have been using Marumi Filters on my lenses for some time now.  They are optically
very well constructed (first priority), thin enough to prevent vignetting, and coated
to resist moisture.  I have tested the filters against B&W and Nikon and see very little,
if any, difference.  I use filters primarily for protection of the lens, but ocasionally
leave the filter on for a shot.  I see very little change in the resolution or color shift.

I like these more than the actual Roomba filters, as these have a screen which really helps prevent debris from clogging the filter as fast and prolongs their life.  It also makes cleaning the filter easier and faster (I use my Dyson to suck the debris out).

Filters are difficult to remove.  They appear to be intended for single use, rather than reusable in the way the original is.

A somewhat over-priced replacement filter. A roll of blue shop towels cut with a utility knife to the correct height will do just as good of a job (in fact that is what I am using now).
