Parts for your 2023 Suzuki Splash-Cabin filter

Cabin filter for a 2023 Suzuki Splash: what it does and how to look after it

Based on technical sources, the Suzuki Splash platform is fitted with a replaceable cabin (pollen) filter. The Suzuki Splash Owner’s Manual (EU, 2013, “Air Conditioner Filter”), the Opel/Vauxhall Agila B Owner’s Manual (sister model, 2012, “Pollen filter”), and OE-quality catalogues from MANN-FILTER and MAHLE all specify a serviceable cabin filter for the Splash/Agila HVAC unit. While Suzuki ended Splash production in the mid‑2010s, vehicles registered or serviced in 2023 use the same HVAC layout and take the same cabin filter.

In the Splash, the cabin filter’s job is to trap dust, pollen, road grime and fine particulates before they enter the cabin. Charcoal (activated carbon) versions also help reduce odours and some exhaust fumes. Keeping this filter fresh protects the heater/air‑con evaporator from clogging, maintains strong airflow, and helps keep demisting quick and clear on chilly mornings.

For Aussie and Kiwi driving, with a mix of dusty back roads, coastal air and seasonal pollen, they recommend replacing the Splash cabin filter every 12 months or around 15,000 km. If the car spends time on unsealed roads, in heavy traffic, or during bushfire season, halve that interval. A quick visual check at each service is a good habit.

Common signs it’s due:

• Weaker airflow at the vents unless the fan is cranked up
• Musty odours when the A/C starts
• Fan noise increases but not much air moves
• Windows fog more easily or take longer to clear

DIY replacement is straightforward and takes about 10–15 minutes:

1. Open the glovebox and unhook the side stops so it can drop down.
2. Pop off the small rectangular cover on the HVAC housing behind it.
3. Slide the old filter out, noting the airflow arrow direction.
4. Vacuum any leaves/debris, then slide in the new filter with arrows aligned.
5. Refit the cover and close the glovebox.

When choosing a replacement, a high‑quality particulate or activated‑carbon filter is worth it for local conditions. During servicing, it’s smart to pair a new filter with an evaporator sanitiser to keep the system fresh and help allergy sufferers breathe easier. If the filter looks clean but airflow is low, have a technician check the blower motor and the evaporator drain as part of regular maintenance.

Where is the cabin filter on a 2023 Suzuki Splash?

It sits behind the glovebox in a vertical slot on the HVAC housing. Drop the glovebox by releasing the side stops, unclip the small access panel, and the filter slides straight out. No special tools are usually needed.

How often should the Splash cabin filter be changed in Australia or New Zealand?

As a rule of thumb, every 12 months or about 15,000 km. If the car sees dusty rural roads, frequent construction zones, or smoke and heavy pollen, consider every 6 months or 10,000 km for best airflow and cleaner air.

Can they fit a charcoal/activated carbon filter to help with odours and smoke?

Yes. Activated‑carbon filters are a direct swap for the standard paper element. They’re a good pick if the Splash is used in urban traffic, during bushfire season, or if occupants are sensitive to odours.
