When to Replace Filters (5 Warning Signs)
Sign 1: Weak Suction Despite Clean Robot
Test: Place hand over suction inlet while robot running. Should feel strong pull.
If weak suction and robot is otherwise clean (brushes, dustbin), filter is likely clogged.
Sign 2: Dreame App Shows Filter Warning
Most Dreame models track filter life hours:
- Yellow warning: Clean filter soon
- Red warning: Replace filter now
- Filter icon flashing: Suction reduced to protect motor
How to check:
- Open Dreame app
- Select your robot
- Go to Settings → Maintenance
- Check filter life percentage
Typical lifespan: 150-200 cleaning hours (about 2-3 months daily use)
Sign 3: Visible Filter Damage
Inspect filter visually:
- ❌ Tears or holes - Replace immediately
- ❌ Dark gray/black color - Fully saturated, replace
- ❌ Hard or crusty - Beyond cleaning, replace
- ❌ Deformed shape - Won't seal properly, replace
- ✅ Light gray - Washable, can continue using
Sign 4: Musty Smell from Robot
Trapped moisture + dust = bacterial growth in filter.
If robot smells musty even after cleaning dustbin and brushes, filter needs replacement.
Sign 5: Time-Based Replacement
Even if filter looks okay, replace based on time:
- Daily use (2+ hours/day): Every 2 months
- Regular use (1 hour/day): Every 3 months
- Light use (3-4x/week): Every 4-6 months
- Washable HEPA (L20 Ultra): Every 6 months after monthly washing
💡 Pro Tip: Buy filters in bulk (packs of 4-6). Saves 30-40% per filter and ensures you always have spares.
Filter Types Explained
HEPA Filter (Primary)
What it is: High-Efficiency Particulate Air filter - traps 99.97% of particles 0.3 microns or larger.
Location: Inside dustbin or behind dustbin slot.
Lifespan:
- Non-washable: 2-3 months
- Washable (some models): Clean monthly, replace every 6 months
Signs it needs replacement:
- Turned dark gray or black
- Feels hard or crusty
- Visible tears or damage
- Strong odor
Cost: $8-15 per filter (OEM), $4-8 (compatible)
Foam/Sponge Pre-Filter
What it is: Coarse filter that catches large debris before air reaches HEPA.
Location: Attached to HEPA filter or separate slot in dustbin.
Lifespan:
- Washable: Clean weekly, replace every 3-6 months
- Non-washable: Replace every 2-3 months
Signs it needs replacement:
- Foam disintegrating or crumbling
- Lost absorbency (stays soggy after drying)
- Visible tears
- 6+ months old
Cost: $3-6 per filter (often sold with HEPA as combo pack)
Cyclone Filter (Some Models)
What it is: Mesh filter in cyclone chamber that prevents dust from entering motor.
Location: Inside robot, not in dustbin (requires partial disassembly to access).
Lifespan: Clean every 3 months, replace every 12 months.
Cost: $10-18 per filter
Note: Not all Dreame models have this. Check manual.

- Press down until clicks closed
- Ensure proper seal
- Reinstall dustbin:
- Slide dustbin back into robot
- Push until definite click sound
- Reset filter counter (Important!):
- Open Dreame app
- Settings → Maintenance → Filter Life
- Tap "Reset" button
- Confirms new filter tracking
✅ Verification Test:
- Run short cleaning cycle
- Check suction (should be noticeably stronger)
- No unusual smells or sounds
Washable vs. Non-Washable Filters
Washable HEPA Filters (L20 Ultra, some newer models)
Advantages:
- ✅ Cost-effective long-term ($15-30 every 6 months vs $15 every 2 months)
- ✅ More environmentally friendly
- ✅ Maintains suction if cleaned regularly
Disadvantages:
- ❌ Requires regular washing (monthly)
- ❌ Must dry 24+ hours before reinstalling
- ❌ Loses efficiency after 6-10 washes
How to Wash:
- Remove filter from dustbin
- Rinse under cold running water (backside to frontside direction)
- Gently tap to remove excess water
- Do NOT scrub or use soap - damages HEPA structure
- Air dry completely (24-48 hours in well-ventilated area)
- Never reinstall damp - causes mildew and motor damage
How Often to Wash: Every 2-4 weeks (when app shows 40-50% filter life)
Non-Washable HEPA Filters (Most Dreame models)
Advantages:
- ✅ No washing maintenance needed
- ✅ Consistent performance throughout lifespan
- ✅ Quick tap-clean extends life slightly
Disadvantages:
- ❌ More frequent replacement (every 2-3 months)
- ❌ Higher long-term cost
Extending Lifespan:
- Tap filter over trash can weekly (removes surface dust)
- Use compressed air (gently, outside only)
- Keep dustbin clean to reduce filter load
- Empty dustbin after every use
Never wash non-washable HEPA! Water destroys filter fibers, reduces filtration to 10-20%.

💡 Our Testing: We've tested compatible filters extensively. For most users, quality compatible filters perform identically to OEM. Save your money unless robot is under warranty.
How to Verify Compatibility
- Check Dreame model number:
- Written on bottom of robot
- Shown in Dreame app → Settings → About
- Match filter part number:
- Check existing filter for part number (small text on edge)
- Enter into Amazon search
- Read product description carefully:
- Should explicitly list your Dreame model
- Example: "Compatible with Dreame L10s Ultra, L10s Pro"
- Check reviews:
- Look for your specific model in reviews
- Filter by "verified purchase"
- 4.5+ star rating ideal
- Verify pack contents:
- Most packs include HEPA + foam pre-filters
- Count should match what you need
Red Flags:
- ❌ "Universal fit" claims (often don't fit well)
- ❌ No model numbers listed

Common Filter Replacement Mistakes
Mistake 1: Washing Non-Washable HEPA
Why it's bad: Water destroys HEPA fiber structure, reducing filtration dramatically.
How to avoid:
- Check if your model has washable HEPA (manual or app)
- If unsure, don't wash - just tap to clean
- Look for "washable" label on filter itself
Mistake 2: Reinstalling Damp Filter
Why it's bad: Damp filter = mildew growth, musty smell, potential motor damage from moisture.
How to avoid:
- Always air dry washable filters 24-48 hours minimum
- Test dryness: should feel completely dry to touch, no coolness
- Keep spare filter set - swap while washing
Mistake 3: Not Resetting Filter Counter
Why it's bad: App continues warning, robot may limit suction unnecessarily.
How to fix:
- Dreame app → Settings → Maintenance → Filter → Reset
- Counter should return to 100%
Mistake 4: Buying Wrong Filter Size
Why it's bad: Wrong fit = air leaks, reduced suction, dust bypassing filter.
How to avoid:
- Write down exact model number before buying
- Compare filter dimensions if possible
- Buy from reputable sellers with good return policy
Mistake 5: Replacing Filter But Not Pre-Filter
Why it's bad: Dirty pre-filter still blocks airflow, negates new HEPA benefit.
How to fix:
- Always replace or wash BOTH filters together
- Buy combination packs (HEPA + foam)
Mistake 6: Overtightening or Forcing Filter
Why it's bad: Can crack filter or damage dustbin housing.
How to avoid:
- Filter should slide in easily with slight resistance
- If forcing needed, check orientation (may be upside down)
- Twist-lock types: twist gently until stops, don't crank
Filter Maintenance Between Replacements
Extend filter life 30-50% with regular maintenance:
Weekly Maintenance (1 minute)
- Tap filter cleaning:
- Remove filter from dustbin
- Tap firmly over trash can (outside)
- Removes surface dust
- Doesn't damage filter
- Clean pre-filter:
- Rinse foam pre-filter under cold water
- Squeeze gently, air dry 2-4 hours
- Reinstall when completely dry
Monthly Maintenance (5 minutes)
- Deep dust removal:
- Use compressed air on HEPA (gentle pressure)
- Blow from clean side toward dirty side (pushes dust out)
- Do this outside or in garage
- Inspect for damage:
- Check for tears, holes, deformation
- Replace if any damage found
- Washable HEPA cleaning (if applicable):
- Follow washing instructions
- Dry 24-48 hours
Best Practices
- ✅ Empty dustbin after EVERY use (reduces filter load by 40%)
- ✅ Store spare filters in dry place (humidity damages HEPA)
- ✅ Replace filters before completely black (maintains optimal suction)
- ✅ Keep cleaning brushes free of hair (less dustbin dust = longer filter life)
- ❌ Don't use vacuum if filter missing (damages motor permanently)
- ❌ Don't expose filters to moisture when not washing
Troubleshooting After Filter Replacement
Suction Still Weak After New Filter
Check:
- Filter installed correctly (no gaps, fully seated)
- Dustbin fully closed and latched
- Main brush clean (hair-free)
- Check for clogs in dustbin air pathway
- Verify new filter is genuine/quality compatible (cheap filters = poor filtration)
If still weak:
- Run diagnostic in Dreame app (some models)
- Check for dustbin sensor issues
- May need internal motor filter cleaning (cyclone filter)
Robot Shows Filter Error Despite New Filter
Solutions:
- Reset filter counter in app (most common fix)
- Reseat dustbin (may not be fully clicked)
- Check dustbin contacts (clean with dry cloth)
- Restart robot (hold power 10 seconds)
- Factory reset app connection (last resort)
Filter Doesn't Fit New Robot
Verify:
- Exact Dreame model number matches filter compatibility
- Orientation correct (some filters are directional)
- Not forcing upside-down filter
If genuinely wrong:
- Return filter, get correct model-specific version
- Check if Dreame changed filter design in newer production runs

Common Questions
Can I clean HEPA filters instead of replacing?
For washable HEPA (L20 Ultra): Yes, rinse monthly and replace every 6 months. For non-washable HEPA (most models): No, washing destroys filter structure. You can tap-clean to extend life slightly, but replacement is required every 2-3 months.
Do I really need to replace filters or is it a money grab?
Filters genuinely need replacement. Clogged filters force motors to work 50-80% harder, causing overheating and premature failure. Motor replacement costs $60-100 vs $8-15 for filters. It's preventive maintenance, not a scam.
What happens if I run Dreame without a filter?
Never do this! Running without filter allows dust to enter motor directly, causing permanent damage within days. Motor repairs cost $60-100+ and may not be possible. Always use a filter, even an old one is better than none.
How do I know if my Dreame has washable HEPA?
Check: (1) Product manual - states washable if applicable, (2) Filter itself - washable filters usually have "washable" printed on edge, (3) Dreame app - maintenance section indicates wash vs replace. If unsure, don't wash - tap-clean only.
Can I use generic vacuum filters from hardware stores?
No, robot vacuum filters are specifically sized and rated. Generic filters won't fit properly and may have wrong filtration rating. Always buy Dreame-compatible filters (OEM or compatible third-party).
Why does my filter need replacing more often than advertised?
Advertised lifespan assumes "average use." Factors that shorten lifespan: (1) Heavy use (2+ hours/day), (2) Pet hair (clogs faster), (3) Hardwood dust (fine particles), (4) Poor maintenance (overfilled dustbin), (5) High pollen area. Adjust replacement schedule to your actual conditions.
