Filters for joints in this category are primarily PURIZE carbon filters, alongside Mascotte and Hybrid filters and wooden mouthpieces. Each filter is inserted at the end of the roll instead of a rolled cardboard tip. They differ in diameter, length, wrapper color, and the number of pieces in a pack. The choice starts with the rolling paper, as it determines what diameter will fit.
Carbon filter instead of cardboard
A regular tip, which is a rolled cardboard, stiffens the end of the roll and prevents material from reaching the mouth. A carbon filter does the same, and inside it has activated carbon from coconut shells. In PURIZE and Mascotte filters, this insert is closed on both sides with ceramic caps, so the filter has no side that needs to be inserted first.
The filter is single-use: one filter for one roll, then to the trash, just like the rolling paper. More about the construction of such a filter is discussed in the text carbon filters: how they work and whether they are worth it.
Filters for joints: diameter and length, or matching to the rolling paper
The diameter determines whether the filter will fit into the rolling paper without pushing the paper apart, and the length determines how much space it will take at the mouthpiece. The diameter is stated in the name of each pack, so the variants are easy to compare.
- XTRA Slim: 6 mm diameter and 25 mm length, for slim and King Size Slim papers; this size has the most colors and packs
- Slim: 7 mm, in between XTRA Slim and Regular
- Regular: 9 mm, for King Size and wide papers, with a looser draw than XTRA Slim
- Regular Short: the same 9 mm with a length of 27 mm, shorter at the mouthpiece
- XTRA Long: 6 mm diameter with a length of 40 mm
- BIG Size: 14 mm, exclusively for King Size Wide papers
- Conical: conical filter, narrowing from 6 mm to 5 mm with a length of 25 mm, designed for cone-shaped rolls
If you do not yet know your size, start with a small pack and only then buy a supply.
Construction and colors
PURIZE and Mascotte filters have the same construction: activated carbon from coconut shells enclosed between two ceramic caps. PURIZE filters are made in Germany. Hybrid filters are constructed differently, as they have cellulose caps, a diameter of 6.4 mm, and a length of 30 mm, and the manufacturer describes their taste as neutral.
The color of the wrapper does not change the construction. The Rainbow, Pink, Yellow, Green, Organic, or White editions have the same filter inside and differ only in appearance. Mascotte Active Colors mixes several colors in one bag, and the PINK edition has all filters in one color.
Trial and bulk packs
The same filter can be purchased in a trial pack and in a supply for months. Small packages have 5 or 10 pieces, typical ones have 50 and 100 pieces, and bulk ones have 250 and 500 pieces. Some variants come in a glass jar, and BIG Size may be packaged in a cardboard tube for 3 pieces.
With a large pack, the closure matters. Activated carbon absorbs moisture from the air, so it is worth sealing the bag after each filter removal and closing the jar. Other small items for rolling can be found in the Accessories category.
What to check on the packaging
The name of the pack says almost everything, but it is worth reading it to the end. Before purchasing, check these items:
- diameter in millimeters, as it determines the fit to the rolling paper
- length, if you are looking for a filter shorter or longer than standard
- shape: cylindrical or conical
- type of caps: ceramic or cellulose
- number of pieces and type of packaging: cardboard, resealable bag, or jar
Frequently asked questions
What size filter fits slim papers?
For slim and King Size Slim papers, the XTRA Slim with a diameter of 6 mm fits. For King Size and wide papers, choose Regular 9 mm, and for King Size Wide, the BIG Size 14 mm filter. Slim 7 mm is in between XTRA Slim and Regular.
Does the color of the filter affect the taste?
No. Manufacturers describe colored and white editions the same way, and the color only pertains to the wrapper. The filling, caps, and diameter remain unchanged, so you choose the color for yourself or for the rolling paper. The Rainbow, Pink, Yellow, Green, Organic, and White editions differ only in appearance, and Mascotte Active Colors mixes several colors in one bag.
Which side to insert the filter?
In PURIZE and Mascotte filters, either side, as the ceramic caps are on both sides of the activated carbon insert, so no side has priority. You insert the filter where the cardboard usually goes and roll the joint as usual. The diameter matched to the rolling paper matters, not which side the filter goes into the roll.
Can the filter be used a second time?
No. The carbon filter is single-use: one filter for one roll, then to the trash. However, wooden mouthpieces are reusable, to which a new filter is inserted each time. The wooden mouthpiece made from oiled American walnut has a socket for either XTRA Slim or Regular filter, depending on the version.
What is the purpose of the wooden mouthpiece?
It is an adapter between the roll and the filter. It has a conical opening at the front for rolls of various thicknesses, and at the back, a socket for either XTRA Slim or Regular filter, depending on the version. It is made from oiled American walnut and sold in packs of 5 pieces. The mouthpiece is reusable, and the filter is replaced with a new one each time.
