Cartridge Filter Kit for So 2, Filter Replacement for Machine Includes 4 Cartridge Filters and 4 Check Valve (4 Set)

I am SO happy these work, what a great value! Any SoClean owner knows the filters are $30 for just one. Sadly, we initially did not follow directions thoroughly. We replaced the filter and check valve and the colored lights still lit up and the error message appeared for "order filter kit". I was so disappointed! I contacted the seller for guidance who immediately offered a full refund. I did not want to get a refund, I wanted the filter kit to work. There didn't seem to be any size issues, it fit perfectly. Then my husband took out the SoClean book, reread the directions and reinstalled the filter kit. Boom, works perfectly now, OUR error. Hold the two buttons simultaneously, and WAIT for the filter installed message to appear on the machine BEFORE you let go of the buttons. Very simple error really, our fault for not paying attention to detail. I highly recommend this filter kit for SoClean owners.

The medical supply place I was buying these from charge more for one than it cost me for a package of 4. These arrived in a timely fashion and work awesome.

I was charged when I ordered and then changed again exact same amount the very next day, I was left without money that I needed. Bank couldn’t help me Amazon couldn’t help me I called and called. I did not get my money back from 2nd charge for a week. Pro-duct is exactly what I needed I got 4 filters & 4 check Val’s for less money than 1 filter & 1 check Val.

Arrived on time, and to my home (Front door), unlike other packages that are delivered by the USPS. Nonetheless, as advertised, already installed, and my Soclean app advises all filters accepted. Highly Suggest!

these cartridge replacement filters and check valves fit perfect, work great, and at a big savings on cost of replacing filters,,,,,received 4 filters and check valves for what I had been paying for one,,great valve...

So far, so good. The filter works with my SoClean2. I just followed the instructions and things went smoothly. One reviewer complained about things not working well, but I didn't have any problems at all.

These SoClean replacement filters are one-third the price of the filters from the SoClean factory. They fit perfectly and I notice no change in operation and performance from the original equipment filters.

I use a SoClean machine for my sleep apnea head gear and CPAP. I love everything about the SoClean machine except the price of the replacement filters. At first, I ordered the replacement filters from a CPAP distributor, paying $30.00 per replacement. After searching Amazon for generic replacement filters, I settled on the Cartridge Filter Kit for So 2, Filter Replacements. I was a bit skeptical about the effectiveness of these filters due to their very low price, roughly one hundred dollars less than the four branded filters. On the first day of use for these filters I was a bit worried as I watched and smelled the air coming from the cleaning machine. These filters have a very different scent from the manufacturer's filters. The true SoClean filters have a very fresh, pleasant smell that fills the air. These replacement filters have a weaker, carbon scent that will take a while to get used to. Since I was worried about the different scent, I had little hope that they would be effective. Well, later that night when it was time to use my CPAP mask I did notice a stronger carbon taste on the face mask. I used the mask thinking that it was not very clean and a sinus infection was in my near future. If you have a CPAP machine you know what I mean when I say I was worried about a sinus infection from a dirty mask. It happens, and it happened much too often before I invested in the SoClean machine. To my surprise, I woke the next morning without any after taste from the generic cleaning filter. And, after using these generic filters for eight months I have yet to get one sinus infection! So, I am happy with my purchase and wish the same results for others. Pleasant dreams!
