Osmio Staff Pick as best Gravity Filter on the market

✓ Average pore diameter ~ 1 micron

The powerful ceramic gravity filter is compatible with all of the Doulton (British Berkefeld) and Big Berkey (and larger sizes) filter housings and makes a fantastic upgrade option as the filters have fantastic performance, particularly with regard to fluoride, hormone and pharmaceutical reduction in water. In other systems, such as the Doulton Super Sterasyl and Doulton ATC Super Sterasyl or the Berkey Black Elements, both of these require either the PF-4 or PF-2 Fluoride and Arsenic Filters (respectively) which take up space in the lower chamber which minimise the space available for storage of filtered water and adds cost to the process.

Superior Flow Rate and Filter Volume

The Coldstream filters are 1" longer and nearly 1" wider and therefore not only contain more filter media resulting in superior filtration, but also much faster flow rates. See how the filters compare in size to the Doulton Gravity Filters:

NSF 42 Certified Components - which guarantees materials are not extracted at all into the filtered water. Despite rumours put about my competitors - this product does not contain BONE CHAR

Disposing of used filters

The filter would need to be smashed the ceramic and media inside should go to rubbish and the plastic ends can be recycled as plastic. Some people use the media and ceramic to compost but I don't because they can have pharmaceutical and hormone traces and I grow food so I would not want that. For the media, it would be best to send that stuff to the landfill.

Product Questions

Can you confirm the filters do not contain aluminium?
Question by: Amy Winchester-Daw on 24 Sep 2021, 12:16
Aluminium is not used in the production of these filters.
Answer by: Irina Orlenko on 2 Oct 2021, 12:33
Hi I have a big berkey. Do i use the gravity water filters with the black berkey filters? As you would use the white flouride berkey filters? Thanks
Question by: Romina on 16 Apr 2022, 07:13
You can use these filters in Big Berkey system. These filters achieve fluoride reduction without the need of additional filters. You need to install them instead black elements in top chamber.
Answer by: Irina Orlenko (Admin) on 18 Apr 2022, 22:57
1. Are these filters compatible with the Travel Berkey?

2. Do they leach anything into the water? I ask as there is a known issue with Berkey PF-2s leaching Aluminium into filtered water.

Thanks for your time.
Question by: Chris R on 21 Dec 2021, 22:48
Thank you for your questions.

The Coldstream Sentry FTO+ 2.9" x 8" Ceramic Gravity Water Filters are compatible with the Travel Berkey system.

Coldstream Sentry FTO+ 2.9" x 8" Ceramic Gravity Water Filters employ different technology to Berkey fluoride reduction filters..
The Berkey Flouride Reduction filter (that screws onto the end of the PF2); uses Ion Exchange technology and therefore Aluminum Hydroxide in exchange for fluoride.
The Coldstream filters use Adsorption to remove fluoride from water through calcium phosphate and carbon and do not use Ion Exchange.

Please do not hesitate to contact us if we can be of further assistance.

Hi, do the Coldstream Sentry 4 Pack of FTO+ 2.9" x 8" Ceramic Gravity Water Filters fit the Big Berkey 8.5 litre model? Thanks in advance

Question by: Lottie on 18 Jan 2022, 19:02
Yes the Coldstream sentry filters can be used in the system instead of the Black Berkey elements, they are fitted in the top chamber.
Answer by: Sharon Little (Admin) on 19 Jan 2022, 09:57
How often should you replace the filters on a coldstream?
Question by: Sharon Howell on 22 Jan 2022, 09:54
It is recommended to replace used Coldstream Filters every 6 months.
