Sadly these are less durable at pressure than the wheel filters without the colored plastic ring. Differences in molding process or different type of plastic housing. They're wonderful so long as you don't

Size is perfect and they arrived super fast. I have two concerns with this product: 1) there are two sides-one smooth and glossy and the other other is felt-like and fuzzy. 2) they are about twice as thick as other brands and distorts too easily. Most likely this happened during manufactureand #1 is causal to #2. I can't help thinking

I use this product for making a small batches of natural perfume from essential oil’s. I’ve been doing this for nine years and I have used thousands of these types of filters for this purpose. I’ve tried several different brands and I’ve never had an issue until I used this one. I could not get one filter to work properly. In fact

Bought this paper to use for soil analysis and filtration. It's VERY slow at filtering and it is rather small, so be sure you're only using it for small test tubes and for very small quantities of water/solution. There were some soil solutions of mine that i had hoped it would clear up the solution but it did not in a few select cases.

Works great for my purposes. I don't use enough to warrant a 50-100 pack, so it's nice they're offering in 10's Never had a problem with these and shipping is on time and depenable. When these aren't available I've ordered the PTFE and the PES versions which have also been good. I like using them fo filter my solution into a sterile

like the 0.22 micron variety, these filters fit well and do not leak at the seam like some others. they are good for filtering out large particles and binders in a project where tablets are used before the final sterile filtration. As a sidebar, trying to bypass the 0.45 micron step only yields frustration and usage of many 0.22 micron

Took a chance on these filters after being turned off by the sky high prices from some of the other name brand filters. I am totally satisfied. There is little to no difference in quality between Biomed’s product and that of the Millepores, Whatmans and others. I will buy

As far as the filter capabilities these work well. The problem with my item was it came in a sealed plastic bag yet it appeared to have gotten moist at one time. They were dry but about half of the filters were sort of warped and not flat which meant I had to get them wet and place them between something very flat and let them completely

These filters are great for filtering my final perfumes and perfume tinctures. I took a star off because the ash content is not listed on the box and I emailed the seller regarding the ash content and received no reply. Other than that these are great. They are bigger than I imagined, which is awesome. They are decent as far as strength

Wow. This is so effective and easy to use and reuse. Allows gas exchange and keeps contamination out. I modify these for my needs. I use a paper punch and punch out a hole in the center. Fill the hole with red RTV high temperature gasket sealer to make a self sealing port. Wax paper does not stick as it is drying. Pressure can to

They are too big for wide mouth jars and had to be cut down in size. Not that big of a deal but say that, dont say they fit wide mouth when they dont. Otherwise good material, but was paying for convenience of not having to cut them

I used it to filter my blueberry wine.

Spring water clogged these up faster than my wine! I first filtered my wine several times, down to .45 microns than used these. I was able to filter at least 300 ml of wine with one syringe adapter thing. Probably more.

I had to add a half a bottle of water to my last bottle

For winterizing rosin these work pretty well. I was using smaller filters (25mm diameter), but these definitely speed up the process. The down side is that out of 20 filters, I have had 3 blowouts which I did not experience with the smaller

These work really well for fine filtration, use for cold brew coffee.
BTW, anyone talking about buying low ash filters for more money generally has no idea what they're talking about. Low ash filters are used when analyzing the filtrate captured will require burning the sample to determine what you've captured. Low ash doesn't mean

New user of a buchner funnel, but the filter papers seem too rigid to seal at the edges. I'll try to add a picture, but the filter paper will not lay perfectly flat in the funnel, and does not soften sufficiently to hug the outer

What I really like the most about these PTFE syringe filters is that they are wall marked for .22um - when working with different requirements for filtration one needs to be able to quickly discern which ones are being used, and many/most of the available offerings out there fail to mark their products.

Not so with these, and I

This is a must have for well water. The only complaint I have is the bracket for mounting to the wall is a little flimsy. The hot water string wound filter is a little hard to find with the metal core. I ended up ordering a new filter directly from the manufacturer. I switched the filter after 6 months and the results are quite

Perfect for an LC jar in mycology use. Allows plenty of air exchange for liquid culture while simultaneously allowing you to shake a jar without worry of leaks or contamination because the filter is liquid impermeable. Less great for grain jars where grains can lodge and block air flow and you need larger holes for GE. Lost 10 grain jars

These work, but not nearly as good as the competition. The larger green filters by Membrane Solutions (33mm diameter / 0.22um STERILE PES) might be 2x the price, but they're at least 5x better. Compared to the green ones, these yellow ones are disappointing.

They are much cheaper, but they struggle to filter even 10mL of any

These filters work perfectly well, but are just made a bit cheap and small details are inferior to a better known name brand filter. For instance, the edges of the filter are simply non-texured plastic, making them hard to install or remove if there is oil on your safety gloves. Just small details like that are kinda a bummer, but overall

I've tried every brand and type of micron filter. This brand has the ability to hold snug to the syringe without stripping and losing its seal. It's hydrophilic and almost every bit passes through less what you want to filter out! Two thumbs

I really like these filters, but the one thing that bothers me is they changed the packaging. They used to be in little compartments in the box. This kept them very neatly organized. Now they are just in a smaller box, and once you start taking them out they get jumbled up, and you have to really work at closing the box. Just kind of

Many of these filters break very easily. I give 3 stars because they cost half as much as similar filters on here. Nearly 50% of these break immediately upon use, so I'm not sure that's even a good deal.
It's hit or miss, some are good filters that hold up and do as good a job as any wheel filter, others break with even light
