PUREFLOW Cabin Air Filter Freshener — Black Rock (2-Pack), Clips into Pleats, Up to 90 Days Odour Neutralizer

PUREFLOW Cabin Filter Air Freshener (Black Rock, 2-Pack) is a compact in-filter scent and odor-neutralizing insert that attaches to your vehicle’s cabin air filter for up to 90 days of continuous freshness.

Replace bulky hanging air fresheners with a low-profile solution that hides inside the pleats of your cabin air filter. The PUREFLOW Black Rock formula blends bright lemon zest and cool mint with warm Tonka bean base notes, while integrated odor-neutralizing agents tackle unwanted smells at their source. The discreet design keeps your dashboard clear and sends a balanced scent through your car’s ventilation system each time air circulates.

How does PUREFLOW attach to my cabin air filter?

The freshener clips directly to the filter pleats so it stays secure without adhesives or loose parts. Its slim profile fits between folds and won’t interfere with filter performance when installed correctly.

• Attaches to pleated cabin filters—no dashboard clips needed
• Low-profile design avoids airflow obstruction
• Works with most standard car, truck, and SUV cabin filters
• Easy to remove and replace when changing the filter

How long will the scent and odor neutralizer last?

PUREFLOW’s patented slow-release system is engineered to provide a steady, balanced scent for up to 90 days under normal conditions. Intensity depends on ventilation settings and how often the HVAC runs; higher airflow can disperse fragrance more quickly.

• Up to 90 days of gradual fragrance release
• Consistent scent output that avoids overpowering bursts
• Performance affected by fan speed and cabin airflow
• Replace with cabin filter changes for best results

What does the Black Rock scent smell like and how does it handle odors?

Black Rock combines bright citrus top notes with cool mint and a subtle spicy-sweet Tonka bean base for a refreshing, layered aroma. The insert also contains odor-neutralizing components that reduce common vehicle smells rather than simply masking them.

• Top notes: lemon zest for a crisp opening
• Mid notes: cool mint to freshen the interior air
• Base notes: Tonka bean adds warmth and depth
• Built-in neutralizers help mitigate smoke, food, and musty odors

Is PUREFLOW easy to use and is it safe for my vehicle?

Installation is straightforward and requires no tools—clip the insert into your cabin filter’s pleats before placing the filter in its housing. The unit is designed to be unobtrusive and compatible with routine filter maintenance; however, always follow your vehicle manufacturer’s guidance when replacing filters and accessories.

• Tool-free installation—clips into filter pleats
• No dangling parts to interfere with cabin layout
• Replace when you change your cabin air filter for consistent results
• Follow vehicle instructions to ensure proper filter seating
