Rolling papers
by Greengo
Greengo Natural Slim Filters are unbleached, biodegradable cellulose filters designed to deliver a smooth, additive-free smoking experience. Each pack contains 200 slim filters measuring 6mm in diameter and 15mm in length — the standard slim size that slots into any rolling paper or pre-rolled cone without fuss. If you've been rolling with torn-up bits of card or skipping filters entirely, these are a proper step up.

Complete your rolling setup with Greengo King Size Slim Rolling Papers — same brand, same unbleached philosophy, and they pair naturally with these 6mm filters. If you prefer a wider gauge, Greengo also makes standard-width filters worth a look.
Most cheap filters you'll find at a petrol station have been bleached white with chlorine. That's cosmetic — it doesn't improve filtration, and it can leave a faint chemical taste on the inhale that you only notice once you've switched to something better. Greengo skips the bleaching entirely. The filters come out a natural off-white/light brown colour, and the first thing you'll notice is the absence of that papery, slightly acrid note on the first drag. It's a small detail, but once you've tasted the difference, going back feels wrong.
The material itself is pure cellulose — the same plant-derived fibre used in cotton and wood pulp, just pressed and shaped into a 6mm cylinder. No activated charcoal, no synthetic binding agents, nothing you can't pronounce. That matters if you care about what you're inhaling, and honestly, you should. The 6mm slim diameter is the standard for slim rolling papers, so compatibility isn't something you need to think about. They fit. Every time.
Here's the honest limitation: these are standard cellulose filters, not activated charcoal ones. They'll catch loose material and cool the smoke, but they're not designed for heavy-duty filtration the way a charcoal filter would be. If you want maximum filtration, charcoal slim filters exist — but they also alter the draw resistance and can mute flavour. Greengo's approach prioritises taste and simplicity, which is exactly why most of our customers prefer them for everyday use.
A pack of 200 sounds like a lot, and it is. If you're rolling 3–4 times a day, that's still roughly 7 weeks of filters from a single pouch. The resealable closure keeps them clean and dry — cellulose absorbs moisture if left exposed, which can make the filters swell slightly and become harder to fit. Keep the pouch sealed and stored somewhere dry, and they'll stay consistent from the first filter to the 200th.
The pouch itself is genuinely pocket-sized. We've seen people stuff a pack into their rolling tin alongside papers and a grinder card without any trouble. Compared to buying filters in rigid plastic boxes, the soft pouch wastes less space and produces less packaging waste — which fits the whole Greengo ethos.
Greengo has built their entire range around one idea: smoking accessories don't need chemical processing to work well. Their rolling papers are unbleached. Their filter tips are unbleached. Even their herbal smoking blend (a tobacco-free mix) follows the same no-additives principle. It's a consistent lineup, and if you're already using one Greengo product, the rest of the range slots in without any surprises.
The 100% biodegradable claim is straightforward — pure cellulose breaks down naturally. That won't save the planet on its own, but it does mean the filter you flick into a bin (not the street, please) will decompose rather than sitting in a landfill for years like a standard acetate cigarette filter. Acetate filters can take 10–15 years to break down. Cellulose? Weeks to months, depending on conditions. It's a genuine material difference, not just marketing.
Each resealable pouch contains 200 individual slim filters. At a few rolls per day, that's easily a month or two of use from a single pack.
They measure 6mm in diameter and 15mm in length. That's the standard slim filter size, compatible with all slim rolling papers and most pre-rolled cones.
Yes. They're made from 100% pure cellulose with no synthetic binders or coatings. Cellulose breaks down naturally in weeks to months, unlike acetate filters which can persist for over a decade.
Most people notice a cleaner, more neutral taste. Bleached filters can carry a faint chemical note — it's subtle, but once you switch to unbleached cellulose, you'll likely pick up on it if you go back.
Absolutely. The 6mm slim diameter works with slim and king size slim papers alike. The 15mm length is short enough that it won't eat into your smoking material.
Keep the pouch resealed and stored somewhere dry. Cellulose absorbs moisture from the air, which can cause filters to swell slightly and fit more tightly in your paper. A dry pouch means consistent performance.
No. Cotton filters use cotton fibres; Greengo Slim Filters use pressed cellulose. Both are natural materials, but cellulose filters tend to offer slightly less draw resistance and a more open airflow compared to dense cotton.
