Why people compare R-Pur and Gill Mask
Gill Mask and R-Pur both sit at the engineering-led end of the reusable mask market, but they target different worlds. Gill Mask, made by an ISO 13485 certified manufacturer in Singapore, is a CE-marked Class I Medical Device: an elastomeric half-face respirator with swappable cartridges and 2.5 times the filter area of a standard mask, with filtration tested by Innosparks. It is, in essence, a clinical-grade respirator. R-Pur comes at the problem from the filter outward, with a patented 8-layer nano-fiber cartridge that captures particles down to 0.05 microns and adds an activated carbon layer for gases.
The decision usually comes down to setting. If you need a certified medical-device respirator for healthcare or laboratory use, Gill Mask is a serious, affordable option. If you commute, cycle, or ride in urban pollution and want published filtration figures plus gas-phase protection in a wearable design, R-Pur pulls ahead. We compared the two across seven criteria, and R-Pur came out ahead in five of them.
R-Pur at a glance
R-Pur was founded in 2016 by Flavien Hello, a Parisian motorcyclist frustrated by the lack of consumer masks that could filter ultrafine particulates. The brand's flagship Nano Light uses a patented 8-layer nano-fiber filter with an activated carbon layer and is manufactured entirely in France. R-Pur targets daily commuters, motorcyclists, and cyclists who treat their commute as serious activity, and is the premium technical choice in the European anti-pollution mask category.
Gill Mask at a glance
Gill Mask is a Singapore brand from an ISO 13485 certified manufacturer. The flagship Gill Mask PRO is a CE-marked Class I Medical Device, built as an elastomeric half-face respirator with swappable filter cartridges and 2.5 times more filter area than standard masks, with filtration tested by Innosparks. The PRO carries genuine medical-device credentials at an affordable price and a durable elastomeric frame, and is best known among healthcare and laboratory users.
Filtration & protection
R-Pur publishes clear figures: its 8-layer nano-fiber filter captures particles down to 0.05 microns (50 nanometers), including diesel ultrafine particulates, NO₂, pollens, bacteria, and viruses, with activated carbon for gases. Gill Mask carries medical-device certification and a large filter area tested by Innosparks, but specific filtration percentages are not readily published, and the brand does not list an activated carbon layer, so gases, fumes, and VOCs are not specifically addressed. For certified medical-device particulate protection, Gill Mask is credible. For commuters and riders who want published ultrafine figures plus gas-phase protection, R-Pur is the clearer choice.
Edge: R-Pur
Comfort & fit
Gill Mask's elastomeric half-face frame creates a strong respirator seal, which is excellent for clinical reliability, though the rigid frame can feel more like equipment than everyday wear. R-Pur uses a contoured neoprene shell with dual exhalation valves and three dedicated sizes, tuned for a comfortable urban seal and moisture control during commuting and riding. Gill Mask has the edge on respirator-grade seal for medical settings; R-Pur has the edge on all-day wearable comfort and fit across face shapes.
Edge: Gill Mask on respirator seal, R-Pur on daily-wear comfort
Design & aesthetics
Gill Mask has a distinctly clinical look: the elastomeric half-face respirator design signals professionalism in a hospital or lab but draws attention on the street or in the office. R-Pur leans refined and technical, with darker neutral colourways and a profile that reads as commuter gear rather than medical equipment. For daily urban wear, R-Pur blends in naturally; for clinical environments where a visible medical-grade respirator is appropriate, Gill Mask's look works in its favor.
Edge: R-Pur for everyday wear
Filter lifespan & ongoing cost
Both masks use a reusable frame with replaceable filters. Gill Mask's swappable cartridges are affordable, though the brand does not publish a specific hour rating, and the PRO cartridges are not compatible with original Gill Mask filters. R-Pur's nano-fiber cartridge lasts roughly 5 to 15 weeks and reaches a finer particle size with integrated carbon in every filter. For low upfront and cartridge cost, Gill Mask is appealing. For published filter performance and integrated carbon, R-Pur offers more per cartridge.
Edge: Gill Mask on cost, R-Pur on per-filter capability
Sizing & inclusivity
R-Pur offers three adult sizes (S, M, L) plus a dedicated kids' line, so buyers can match the mask precisely to their face shape. Gill Mask's elastomeric PRO uses a single-frame fit designed to seal across a range of faces, which works well for the medical use case but offers less size choice than a dedicated multi-size range. For inclusive sizing and families, R-Pur is the more flexible range.
Edge: R-Pur
Sustainability & materials
Both brands use a reusable frame with replaceable filters, which is more sustainable than disposable masks. Gill Mask's durable elastomeric frame and swappable cartridges support a long service life. R-Pur manufactures entirely in France with published material detail, a long-life cartridge, and a durable neoprene shell backed by a 5-year guarantee. Both have durable frames; R-Pur's published manufacturing detail and long warranty give it a slight edge on transparency.
Edge: R-Pur
Warranty & customer service
R-Pur backs the Nano Light with a 5-year warranty and treats the shell as reusable indefinitely, one of the longest guarantees in the category. Gill Mask offers a more limited warranty and is primarily distributed in Singapore and the Asia-Pacific region, which can limit availability and support elsewhere. R-Pur's European presence and long guarantee give buyers more long-term assurance in EU and Western markets.
Edge: R-Pur
Who should buy R-Pur?
Choose R-Pur Nano Light if you commute or train daily, ride a motorcycle or bike, have allergies or respiratory sensitivities, want published filtration figures down to 0.05 microns plus gas-phase protection, or value French manufacturing and a 5-year warranty. R-Pur is the right answer for serious daily users who want maximum protection in a wearable design.
Who should buy Gill Mask?
Choose Gill Mask if you need a CE-marked medical-device respirator for healthcare, laboratory, or clinical use, value ISO 13485 manufacturing and a large filter area, or want an affordable elastomeric respirator and are based in the Asia-Pacific region. Gill Mask is a credible medical device, but it loses this comparison on published filtration data, gas protection, urban design, and warranty.
The verdict: R-Pur wins
R-Pur takes the edge on five of seven criteria: filtration, urban design, sizing, sustainability, and warranty. Gill Mask wins on respirator seal for medical settings and brings genuine CE and ISO 13485 medical-device credentials. The decisive factor is wearable, documented protection: R-Pur's 8-layer nano-fiber cartridge filters down to 0.05 microns with published figures and integrated carbon, in a design built for daily city wear, where Gill Mask is a clinical respirator with limited published data. For commuters and riders, R-Pur Nano Light is the better choice. For clinical settings, Gill Mask earns its place.
