01
Quick answer: which chimney type?
- 5-year total cost. Autoclean ₹22k–₹35k against filter ₹15k–₹25k, filter replacements included.
- Maintenance. Autoclean needs the oil collector emptied monthly. Filters need washing every two weeks.
- Power. Autoclean draws an extra 200W during 15-minute heat cycles. Filters draw nothing extra.
THE SHORT VERSION
Autoclean buys you less mess and more convenience, and the ₹8k–₹15k premium is defensible for a busy household. Filter is the pick for heavy frying on a tighter budget.
Two-sided summary
AUTOCLEAN (FILTERLESS)
- Less messy day to day
- Sleek design with no visible filters
- Self-cleaning heat cycle
- No filter replacement costs
- Suits busy households
FILTER-BASED (BAFFLE)
- ₹5k–₹15k cheaper to buy
- Built for heavy Indian frying
- Excellent grease separation
- No extra electricity for heat cycles
- Predictable maintenance schedule
02
What changed in 2026
- Motion sensor auto-on. New autoclean models from Elica and Faber start when you enter the kitchen zone.
- Oil collector indicator. 2026 autoclean chimneys warn by LED at 80% full, which prevents overflow.
- Higher CFM at entry level. Entry models now offer 1,200+ CFM, against 900–1,000 CFM in 2023.
- Better baffle filters. Curved designs improve grease separation by 15–20% over flat ones, with less noise.
- Smart app control. Mid-range chimneys from ₹18k add WiFi for remote control and cleaning reminders.
- Gesture control at budget. Wave-hand control now appears from ₹15k, having been premium-only in 2023.
- Hotter cleaning cycles. 2026 autoclean models run 60°C cycles rather than 45°C, which liquifies oil better.
03
How each type works
Both types pull kitchen smoke and grease out of the room. They differ entirely in what happens to the grease afterwards.
AUTOCLEAN (FILTERLESS)
- A heating plate plus an oil collector tray
- The heat cycle melts grease and channels it away
- Depends on a large inlet and constant airflow
- No removable baffle or mesh filters
FILTER-BASED
- Baffle or mesh filters physically trap grease
- Baffle is the preferred design for Indian frying
- Mesh clogs faster and needs cleaning more often
- Purely mechanical filtration, no power involved

Five-year total cost of ownership
Purchase, plus installation, plus annual running costs across five years. Every figure below includes electricity, cleaning, filters and servicing.
| Usage | Autoclean | Baffle filter | Mesh filter |
|---|---|---|---|
| Light, 15 min a day | ₹22,748 | ₹18,730 | ₹16,730 |
| Moderate, 30 min a day | ₹24,999 | ₹20,960 | ₹20,460 |
| Heavy, 60 min a day | ₹29,498 | ₹25,420 | ₹26,420 |

WHAT THE NUMBERS ACTUALLY SAY
- Electricity barely matters. Every type lands at ₹150–₹600 a year.
- Baffle filters run ₹4,000–₹5,000 cheaper over five years, consistently.
- Mesh is cheapest to buy but overtakes baffle under heavy use, once replacements land.
- Autoclean costs more upfront and then holds steady.

Head-to-head feature comparison
| Aspect | Autoclean | Baffle filter | Mesh filter |
|---|---|---|---|
| Purchase price | Higher, ₹15k–₹35k | Moderate, ₹8k–₹25k | Lower, ₹6k–₹20k |
| Daily maintenance | Low; empty the tray monthly | Moderate; wash filters every 2–4 weeks | High; wash weekly or fortnightly |
| Grease handling | Heat cycle melts it into a tray | Excellent separation, easy to wash | Good, but clogs quickly |
| Heavy Indian cooking | Good; heat cycles cope with build-up | Excellent; designed for it | Fair; needs constant cleaning |
| Filter replacement | None | Rarely — very durable | One or two in five years |
| Electricity use | Motor plus heat cycle | Motor only | Motor only |
| Appearance | Sleek, no visible filters | Visible baffle filters | Visible mesh filters |

Annual electricity cost
All figures at ₹8 per kWh. The motor dominates; the heat cycle is a rounding error.
| Usage pattern | Motor cost | Autoclean heat cycle | Total (autoclean) |
|---|---|---|---|
| Light, 15 min a day | ₹146 | ₹4 | ₹150 |
| Moderate, 30 min a day | ₹292 | ₹8 | ₹300 |
| Heavy, 60 min a day | ₹584 | ₹16 | ₹600 |

THE HEAT CYCLE IS NOT AN EXPENSE
Autoclean heat cycles add ₹4 to ₹16 a year. That is far less than the difference in purchase price or in maintenance, so it should not influence the decision at all.
08
Installation and performance
Installation quality affects suction more than the CFM rating does. These four apply to every chimney type.
DUCT AND INSTALLATION
- Keep duct runs short, with two bends or fewer
- Use smooth-walled metal duct, around 150mm
- Seal every joint with aluminium tape
MOUNTING AND HEIGHT
- Mount 24 to 30 inches above the hob
- Follow your model's manual for exact clearance
- Fit a proper external cowl or rain cap
USING IT WELL
- Start it two to three minutes before heavy frying
- Use high speed only when you need it
- Turn it on for tadka and tempering every time
EXTERNAL VENTING
- Give the duct a slight upward slope so it cannot drip back
- Installation quality decides long-term performance
- Budget ₹2,500–₹3,500 for professional installation
09
Which chimney should you choose?
CHOOSE AUTOCLEAN IF YOU
- Prefer low maintenance. Filter cleaning is not for you.
- Value the look. No visible filters.
- Are short on time. Minimal daily upkeep.
- Have budget room. ₹4k–5k more upfront.
CHOOSE BAFFLE IF YOU
- Cook heavy Indian food. Frying, tadka, masala.
- Watch the budget. Lower upfront cost.
- Do not mind washing. Periodic filter cleaning is fine.
- Want durability. It holds up for years.
CHOOSE MESH IF YOU
- Have a tight budget. The lowest entry price.
- Cook light. Mostly boiling and steaming.
- Clean regularly. Frequent maintenance suits you.
- Plan to upgrade. A starter option.
OUR RECOMMENDATION
For most Indian kitchens doing moderate to heavy cooking, a baffle filter chimney gives the best balance of cost, performance and durability.
Move up to autoclean if convenience matters more than ₹4k–₹5k. Consider mesh only for light cooking or as a deliberate starter.
For CFM sizing and the rest of the specification, read the kitchen chimney buying guide. For duct routing in detail, see chimney suction and ducting.

Frequently asked questions
Are autoclean chimneys really maintenance-free?
No chimney is. Autoclean models still need the oil tray emptied — weekly to monthly depending on how much you cook — and periodic heat cycles. They do need far less hands-on cleaning than a filter system.
Which type works better for heavy Indian frying and tempering?
Baffle filters. They are designed for high grease loads from frying, tadka and masala work, and separate grease far better than mesh does.
How much do replacement filters cost over time?
Baffle filters rarely need replacing — they are very durable. Mesh filters may need one or two replacements in five years under heavy use, at roughly ₹1,500 each. Autoclean has no filter cost but a higher purchase price.
Do autoclean chimneys use much more electricity?
No. The heat cycles add ₹4 to ₹16 a year. Motor consumption, at ₹150 to ₹600 a year, is identical across all types and dominates the bill.
Which offers the best value over five years?
It depends on usage. For light cooking, mesh is cheapest. For moderate to heavy cooking, baffle gives the best balance of cost, performance and durability. Autoclean earns its premium only if you value the convenience.
Can I retrofit autoclean to my existing filter chimney?
No. The two use completely different internal designs. Heating elements, oil collection and airflow paths are built in at manufacture and cannot be added later.
A note on these figures
Cost estimates are based on 2024–2025 Indian market research. Verify current prices, installation charges and your local electricity tariff against the specific model before buying.
