The nasal cannula is included. Yes, we do ship to Australia.

No the bottles uses a spe pem membrane method so it will not allow the pH influencing gases through it, just h2

Good question! The carbon can be crushed and disposed with your garden waste or can be added to flower beds (it will improve soil drainage and will slowly biodegrade); the plastic cups can be disposed in the recycling bin.

Aluminium is not used in the production of these filters.

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.

Yes the Coldstream sentry filters can be used in the system instead of the Black Berkey elements, they are fitted in the top chamber.

It is recommended to replace used Coldstream Filters every 6 months.

The filters can have different filtration speed, with most of filters falling within 1 to 2 litres per hour. But it is normal for some filters to be slower or faster than average range.
Would you be able to time each filter?

Each Coldstream Sentry FTO+ filter measures 2.9" x 8", It has a 1/4" BSP threaded connector, (which has a diameter of 13.16mm).

We would advise checking both the diameter of the filter fitting hole on your system and the depth of the top filter chamber of the system to ensure you have the correct size fitting hole and sufficient depth to accommodate the filters.

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.
