As of Aug 2026, Unbox Health has lab tested and rated 3 products in the Filter Coffee category.
We buy every product from the open market, with no brand involvement. Every product is tested at up to 3 NABL-accredited labs. Products are then rated D to A+, based on the following dimensions: their label accuracy, their toxicity and their nutritional profile (in the case of food products). All lab reports are published.

Filter coffee is a South Indian style brew made by percolating hot water through ground coffee, often blended with chicory, in a metal filter. It is generally fine as part of a balanced diet, and the coffee itself contains antioxidant compounds similar to other brewed coffee styles. What affects its health profile most is added sugar and the proportion of milk used, rather than the coffee-chicory blend itself.
For most healthy adults, one to two cups of filter coffee daily is unlikely to cause problems, though high daily intake can contribute to disturbed sleep, acidity or increased heart rate in sensitive individuals. Filter coffee often carries more caffeine per cup than instant coffee due to stronger decoction strength. People with acid reflux, anxiety or heart conditions should watch their intake and consider reducing frequency if symptoms appear.
This ratio refers to the proportion of coffee to chicory in the blend, so an 80:20 pack contains 80 percent coffee and 20 percent chicory root by weight. A higher coffee percentage generally means a stronger, more aromatic brew and a higher price point. FSSAI requires this blend ratio to be declared on pack, making it one of the clearest indicators of quality when comparing filter coffee brands.
Yes, legally it should. Under FSSAI rules, the term "Pure" can only describe single-ingredient foods, meaning coffee-chicory mixtures are strictly prohibited from claiming "Pure Coffee". To ensure compliance, check that the ingredient list lists "100% Coffee" with zero chicory, or refer to Unbox Health's independent lab data to verify actual coffee content.
Chicory is not considered harmful for most people and is a permitted ingredient under FSSAI norms when its percentage is declared. It is added mainly for cost efficiency and a distinct earthy flavour that many South Indian filter coffee drinkers prefer, not as a hidden filler. The main consideration is transparency, since a higher chicory share means comparatively less actual coffee and caffeine in each cup.
Filter coffee generally offers a richer decoction and stronger aroma due to fresh brewing, while instant coffee wins on speed and consistency across cups. Neither is clearly healthier for most people's daily diet, since both depend heavily on added sugar and milk quantity for their overall nutritional impact. Choose filter coffee if taste and ritual matter more, and instant coffee if convenience is the priority.
Look for a clearly declared coffee-chicory ratio, ideally 80:20 or higher coffee content for a stronger brew, along with freshness indicators like roast or packing date. Avoid packs that mention "filter coffee" without disclosing any blend ratio, since this can hide a higher chicory share. Comparing tested composition rather than relying on packaging language gives a more reliable sense of quality before buying.
Check the declared coffee-to-chicory ratio, roast type, and whether it is ground for filter use or a coarser grind meant for other brewing methods. FSSAI mandates that blend ratios and any additions appear on the ingredient list, so this is the most reliable starting point over marketing terms like "premium" or "traditional." Comparing this against independent lab-tested data adds further confidence before purchase.
Yes, FSSAI permits chicory blending in coffee products but requires the coffee-to-chicory ratio to be declared on the label, since undeclared or mismatched ratios would count as mislabeling. This regulation exists precisely because chicory is cheaper than coffee, creating an incentive to under-declare it. Unbox Health independently tests filter coffee blends through NABL-accredited labs to verify whether the actual ratio matches what is printed on pack.
There is no universal "best" filter coffee since taste, chicory tolerance and budget vary by household, but a stronger pick has a high declared coffee percentage, accurate blend labelling and a fresh roast date. Rather than trusting terms like "premium" or "authentic" at face value, compare brands on their actual tested coffee content. Unbox Health independently tests filter coffee brands to verify whether label claims on blend ratio hold up.
