Buy the Levoit Vital 200S-P if you want phone control, schedules and the lower purchase price; buy the Coway Airmega AP-1512HH Mighty if you never want to open an app and like the idea of one predictable filter order each year. Airflow is close (250 vs 233 CFM smoke CADR), so the real split is how you want to run the purifier and how quickly the Vital's filter loads in your home.
The short answer
Choose the Vital 200S-P if you want to schedule it, switch it on from the couch or another room, use Pet Mode, or spend $130 to $180 rather than about $240.
Choose the Mighty if you want a purifier with no account, no Wi-Fi setup and no app updates, it's going to someone who will only ever press one button, or you find it on sale near $160.
| Compared | Vital 200S-P | AP-1512HH Mighty |
|---|---|---|
| CADR smoke / dust / pollen | 250 / 254 / 289 CFM | 233 / 246 / 240 CFM |
| Room at 4.8 air changes/hr | ~388 sq ft | ~361 sq ft |
| Maker's noise range | 23 to 54 dB | 24.4 to 53.8 dB |
| Maximum rated power | 51 W | 77 W |
| Control | Buttons plus VeSync app and schedules | Buttons only; colored air-quality light |
| Ionizer | None listed | Yes, can be turned off |
| Genuine filter | Vital 200S-RF, $49.99, 6–12 months (listing); ~12 per manual | AP-1512HH-FP set (1 HEPA + 2 carbon), ~$55–60, yearly |

| Typical price | $130–$180 | $239.99 list, ~$160 on sale |
What the app adds, and what it costs you
Levoit's VeSync app gives the Vital remote on and off, fan control and schedules, which is handy for starting the purifier before you get home or quieting it at a fixed bedtime. Pet Mode, which alternates speed 3 and speed 2, and the light sensor that blanks the display in a dark room are built into the purifier, not the app, although that dark-room feature (Light Detection) ships switched off and is turned on from the app.
The trade is the usual one for connected appliances. An account, a Wi-Fi password and app permissions come with it, and a recurring complaint in Levoit owner reviews is the VeSync connection dropping and needing to be paired again. None of that stops the purifier cleaning; it just means the convenience isn't always there.
The Mighty skips all of it. It has a sensor-driven auto mode, a colored air-quality light and an eco mode that shuts the fan off once the air is clean, and that's the entire interface. For a grandparent's room, a rental with patchy Wi-Fi, or anyone who distrusts another app, that is the selling point. If you like the Mighty but do want an app, Coway sells the AP-1512HHS, which takes the same filter set.
Filter cost is closer than the sticker suggests
The Vital's filter is cheaper per piece, but the Mighty's is cheaper per month if the Vital's has to be changed often.
- Coway Airmega AP-1512HH Filter Set: about $55–60 at Coway direct, one set per year (the HEPA lasts about 12 months; the two carbon sheets cover six months each). Older estimates of about $45 a year are out of date.
- Levoit Vital 200S Replacement Filter: $49.99, about every 12 months per the Vital's manual, or 6 to 12 per the filter listing. That works out to about $50 a year at the long end, about $67 at nine months and about $100 at six.
So the Vital's filter is cheaper to run only when it lasts more than about ten months. The listing's range is wide because the bonded HEPA and carbon block wears at very different rates in a quiet bedroom and a house with two shedding dogs. The Mighty's set has the same yearly cadence in both, with the carbon sheets swapped mid-year. See the AP-1512HH filter set page for fit details.
Three-year totals
Assumptions: the Vital at $155 (middle of its range), the Mighty at $239.99 list or about $160 on sale; the first filter in the box; Mighty filter sets at about $60. Electricity for the Vital is 24/7 on speed 2 at $0.17/kWh, using HouseFresh's measured 8.01 W.
| 3-year cost | Vital 200S-P | Mighty at list | Mighty on sale |
|---|---|---|---|
| Purchase | ~$155 | ~$240 | ~$160 |
| Filters | 3 at 9 months = ~$150, or 5 at 6 months = ~$250 | 2 sets = ~$120 | 2 sets = ~$120 |
| Purchase plus filters | ~$305 to ~$405 | ~$360 | ~$280 |
| Electricity | ~$36 on speed 2 | Coway publishes only the 77 W maximum | Same |
On a typical nine-month filter cycle, the Vital is the cheaper machine by about $55 against a full-price Mighty. Put it in a heavy-shedding home and its filters run every six months, and a Mighty bought on sale undercuts it by roughly $125. The Mighty's lower-speed draw isn't published, so electricity can't be set side by side; the 77 W maximum, run nonstop, would be about $115 a year, a ceiling no bedroom setting approaches.

How each handles real rooms
Full-speed air changes per hour, 8 ft ceilings:
| Room | Vital 200S-P | AP-1512HH Mighty |
|---|---|---|
| 12 x 14 bedroom (168 sq ft) | 11.2 | 10.4 |
| 14 x 18 bedroom (252 sq ft) | 7.4 | 6.9 |
| 16 x 24 living room (384 sq ft) | 4.9 | 4.5, slightly short |
In bedrooms the difference is academic: both have more than enough capacity and will idle on low most of the night. The 16 x 24 living room is the one case where the Vital's extra 17 CFM tips it over the 4.8 target and the Mighty falls just under. With a 9 ft ceiling, the coverage limits drop to about 344 sq ft for the Vital and 321 for the Mighty.
The ionizer question
The Mighty ships with an ionizer you can switch off; the Vital lists only mechanical filtration. The Mighty's rated CADR doesn't depend on the ionizer, so leaving it off gives up nothing on paper. If you'd rather not own ion-producing hardware at all, that's a point for the Levoit. Our explainer on ionizer and ozone safety covers the background.
Which one to buy
Pick the Vital 200S-P for most new buyers: it costs less, rates higher on airflow, and the app is there if you want it and ignorable if you don't. Pick the Mighty if a no-app machine is the point, or if a sale brings it near $160 and the house has pets that would force the Vital's filter onto a six-month schedule.
If neither fits, the Coway Airmega Mighty2 is the third option: no app and no ionizer, 240 CFM, a quieter 19 dB floor on Coway's spec sheet, and a single $69.99 cartridge a year, at $269.99 list. For a bedroom under about 220 sq ft, the Levoit Core 300S does the job for around $100. The broader brand question is covered in Coway vs Levoit.
Frequently asked questions
Is there a Coway Mighty with an app?
Yes, the AP-1512HHS. It is the Wi-Fi version of the original Mighty and uses the same AP-1512HH filter set. The standard AP-1512HH, and the newer Mighty2, are button-only.
Does the Levoit Vital 200S-P need Wi-Fi to work?
No. The purifier has its own control panel, so the VeSync app is optional. It adds remote control and schedules on top of what the unit does by itself.
Which is quieter, the Vital 200S-P or the Coway Mighty?
On paper they are almost identical: Levoit rates the Vital at 23 to 54 dB and Coway rates the Mighty at 24.4 to 53.8 dB. Neither maker publishes per-speed figures that would settle it, so expect a similar experience in a bedroom.
What comes in the Coway Mighty filter set?
The genuine AP-1512HH-FP set bundles one HEPA filter with two carbon sheets, sized for a year: the HEPA lasts about 12 months and each carbon sheet about 6. Buying the set once a year is the simplest way to stay on Coway's schedule.
Is the Coway Mighty's ionizer on by default?
The Mighty has an ionizer, and it can be switched off. Its rated CADR comes from the HEPA and carbon filters, so turning it off doesn't cost you rated cleaning. The Vital 200S-P lists no ionizer at all.
