Helps capture airborne smoke particles your fan may miss
Made for cat owners who smoke or vape indoors
Adds filtration beyond an open window alone
Quiet, simple step while the room clears
LeStrova was made for the part careful cat owners know is missing: what happens to the smoke that never reaches the window. It gives you one simple, cat-conscious filtration step for the air around your smoking area—so you are not relying only on distance, a fan, or hoping the room is clear enough for her to return.

“Most cat owners already open a window, run a fan, and keep smoke away from their cat. The missing piece is what happens to the smoke that never reaches the window. LeStrova adds active filtration for the airborne particles you cannot see—so you are not relying on distance, ventilation, or visible smoke alone.”
LeStrova uses active airflow and a deep, replaceable cylindrical HEPA filter to capture airborne particles from the air passing through it.
Its compact design is made to sit near the window, couch, desk, bedside table, or other area where indoor smoking or vaping happens. An optional ion mode works alongside the filtration, while the replaceable physical filter performs the essential collecting.
LeStrova is USB-powered, quiet enough for nighttime use, and designed to add filtration beyond simply opening a window or pointing a fan outside.
Under normal use, replace the filter approximately every 1-2 months. With frequent indoor smoking or vaping, it may need replacing sooner. Check it regularly and replace it when it becomes heavily discolored, dirty, or airflow begins to weaken.
Before smoking or vaping indoors, place LeStrova close to the source without blocking the air intake.
Turn it on before lighting up, open the window, direct every exhale outside, and keep your cat out of the room while smoke is actively being produced.
Leave LeStrova running afterward so nearby room air continues passing through the filter before allowing your cat to return.
For best results:
- Position it close to where the smoke is produced.
- Keep doors and windows arranged to move polluted air outdoors.
- Replace the filter when it becomes visibly dirty or airflow noticeably decreases.
- Continue using your fan, Smoke Buddy, and other precautions.
- Smoke outdoors whenever possible.
LeStrova adds an extra filtration layer. It does not make indoor smoking harmless.
✓ Built for the Smoke Your Window May Miss
An open window helps, but not every particle follows one narrow path outside. LeStrova actively pulls nearby air through a physical filter instead of waiting for smoke to reach the window on its own.
✓ Adds More Than Distance Alone
Keeping your cat across the room changes where she is sitting. It does not filter the air moving between you. LeStrova gives airborne particles a physical filter to pass through.
✓ Made for Careful Cat Owners Who Already Try
LeStrova fits alongside the precautions you already use: open windows, outward-facing fans, closed doors, Smoke Buddies, secure cannabis storage, and keeping your cat away from active smoke.
✓ Replaceable Cylindrical HEPA Filtration
The surrounding filter design gives incoming air multiple layers of dense filter material to move through, helping trap airborne particles before they continue circulating through the room.
✓ Quiet Enough for Nighttime Routines
Run it near the bed, desk, couch, or window without adding a loud appliance to the room while you relax or sleep.
✓ Compact and USB-Powered
Its small tabletop design makes it easy to move wherever you normally smoke, vape, work, or spend time with your cat.
✓ Helps You Act Before the Warning
You should not have to wait for one dry cough, a missed jump, strange wobbling, breathing trouble, or a frightening veterinary visit before improving the air around her.
✓ Works Alongside the Responsible Plan
Ventilation, keeping your cat away, secure storage, veterinary guidance, and smoking outdoors still matter. LeStrova fills the filtration step that an open window and fan cannot provide by themselves.
When should I run LeStrova?
Turn it on before smoking or vaping, keep it running during the session, and continue running it afterward while the room clears.
Place it close to the smoking area without blocking the intake. The closer it is to the source, the sooner nearby air can begin moving through the filter.
I already open a window and use a fan. What is LeStrova adding?
Keep using both.
A window gives polluted air an exit, and a fan helps push air toward it. LeStrova adds a physical collection step by pulling nearby air through a replaceable filter.
A fan moves particles.
LeStrova gives particles passing through it somewhere to be trapped.
Can I leave my cat in the room if LeStrova is running?
No.
LeStrova should not be used as permission to expose your cat to active smoke. Keep her outside the room while smoking or vaping and allow the purifier and ventilation more time to work before she returns.
Smoking outside remains the lowest-exposure option.
Does LeStrova prevent feline asthma, cancer, or THC poisoning?
No air purifier can guarantee that a cat will never become sick.
LeStrova is not a medical device, treatment, or antidote. It is designed to help capture airborne particles from air passing through its filter.
If your cat is coughing, wheezing, stumbling, unusually sedated, confused, trembling, struggling to breathe, or behaving abnormally, contact a veterinarian. Do not rely on a purifier to treat symptoms.
Isn’t the real THC danger only if my cat eats cannabis?
Eating flower, edibles, oils, or concentrates can create a serious exposure risk, so every cannabis product should be stored securely.
But keeping the stash closed does not filter the room’s air. LeStrova is designed for owners who also want to reduce airborne smoke particles near the source.
What if my cat stays across the room?
Across the room is not outside the room.
Distance may reduce direct exposure, but it does not measure what is moving through the shared air. Keep your cat outside the room while smoke is actively being produced.
Does it remove the weed smell?
LeStrova’s main purpose is particle filtration, not masking odor.
A HEPA filter targets airborne particles. Odor-causing gases may require activated carbon or additional ventilation, so do not judge air quality by smell alone.
What does the ion mode do?
The optional ion mode works alongside the purifier’s airflow and filtration.
The replaceable physical filter remains the essential collecting step. For that reason, LeStrova should always be operated with the filter correctly installed.
How often should I replace the filter?
Replacement timing depends on how often it runs, the amount of airborne pollution, and the environment in which it is used.
Check the filter regularly. Replace it when it appears heavily loaded, airflow decreases, or according to the replacement guidance supplied with your unit.
Can I use LeStrova if my cat already has asthma or another respiratory condition?
You can use air filtration as part of the home environment, but follow your veterinarian’s plan first.
LeStrova does not replace medication, inhalers, examinations, imaging, emergency treatment, or professional veterinary advice.
Is this only for people who smoke joints?
No.
LeStrova can be used near areas where people smoke flower, use bowls or bongs, or vape indoors. Different methods may produce different pollutants, but visible smoke is not the only reason to ventilate and filter the room.
What if smoking outdoors is not always realistic?
Keep your cat outside the room, open the window, use an outward-facing fan, direct exhaled smoke outdoors, secure all cannabis products, and run LeStrova close to the source before, during, and after the session.
LeStrova reduces the gap in your routine. It does not remove every risk created by indoor smoking.
Try LeStrova as part of your real indoor-air routine for 30 days.
Use it beside the window, couch, desk, or other area where smoking or vaping happens. Continue using ventilation and keep your cat away from active smoke.
If you do not believe LeStrova added a useful layer of active particle filtration beyond your window and fan, you are protected by our 30-day money-back guarantee.
Indoor Smoke Risks for Cats
Figures come from published indoor-air and feline-health research. The cancer findings involved tobacco smoke, not cannabis smoke, and do not prove smoke caused every case.
LeStrova is for the air-clearing step careful cat owners were missing

You got questions, we got answers
Answers for open windows, fans, hidden smoke, and the indoor-air routine cat owners used to guess through.
LeStrova Ion Air Purifier is used around indoor smoking or vaping to help capture airborne particles your window and fan may miss. Cat owners run it before, during, and after sessions while keeping their cat away from active smoke.
Place LeStrova near the window, couch, desk, bedside table, or smoking area. Keep the air intake unobstructed and position it close to where smoke is produced.
Smoke does not always travel directly into the fan and out the window. LeStrova uses active airflow to pull nearby room air through a replaceable cylindrical filter, helping trap airborne particles instead of allowing them to keep circulating.
Run LeStrova before lighting up, throughout the session, and afterward while the room continues clearing. Many cat owners keep it near their usual smoking area so the filtration step does not get skipped.
