Comparison Insights: The Top 3 Performers
When I look back at my testing logs, three units clearly stand out for specific scenarios. Here is how they stack up against each other:
- Levoit Vital 100S-P vs. ECOSELF HAP603: The Vital 100S-P is the superior choice for ease of integration thanks to its native VeSync support that works beautifully with Home Assistant. However, the ECOSELF HAP603 blows it out of the water regarding raw coverage, handling nearly double the square footage. If you have a massive open floor plan, the ECOSELF is your beast, but for a standard living room with pets, the Levoit’s specialized pet mode makes it more practical.
- Levoit Core 200S-P vs. Levoit Vital 100S-P: Both are “smart,” but the Core 200S-P is significantly more compact, making it the better choice for a nightstand. The Vital 100S-P offers superior PM2.5 sensor accuracy and a much higher CADR. You are essentially choosing between discreet placement and high-performance scrubbing.
- ECOSELF HAP603 vs. ECOSELF HAP609: These are siblings in the same ecosystem, but the HAP603 is the all-around power leader for huge rooms. The HAP609 is the “refined” choice, offering a quieter sleep mode (20dB vs 22dB) and a much more intuitive 24-hour timer. If you’re putting it in a bedroom, get the 609; if it’s for a basement or workshop, the 603 is the winner.

My Buying Guide for Home Assistant Enthusiasts
Integration Protocols Matter
I’ve learned the hard way that not all “smart” purifiers are created equal. When looking for the best air purifier for home assistant, prioritize devices using the VeSync or Tuya ecosystems. VeSync (Levoit) usually has a very stable community integration. If you choose a “dumb” unit like the Core 300, make sure you have a high-quality Zigbee or Z-Wave smart plug with energy monitoring so you can still “see” if the device is on based on its power draw.
Don’t Overlook the Sensors
A purifier is only as good as the data it uses to make decisions. I always look for units with built-in PM2.5 infrared or laser sensors. These allow you to create automations in Home Assistant like: “If PM2.5 is above 20, turn fan to High until it drops below 5.” Units with real-time displays, like the ECOSELF models, provide better telemetry for your dashboards.
Common Questions About Best Air Purifier for Home Assistant
What is the Best Air Purifier for Home Assistant that supports local control?
Most Levoit purifiers use the VeSync integration, which currently relies on a cloud API. However, many enthusiasts use the “LocalTuya” or “Tuya-Local” integrations for ECOSELF or other Tuya-based brands to achieve faster, local-only control without relying on external servers.
Can I track filter life within the Home Assistant dashboard?
Yes! For smart models like the Vital 100S-P or Core 200S-P, the filter life percentage is usually exposed as a sensor entity. I personally set up a notification to my phone when the filter hits 5% so I never forget to order a replacement.
Do I need a smart air purifier, or can I use a smart plug?
You can absolutely use a “dumb” purifier like the Levoit Core Mini with a smart plug. The only downside is you won’t get the PM2.5 data or the ability to change fan speeds remotely. I recommend a smart plug for small rooms and a native smart purifier for large areas where sensor data is more valuable.
How often should I clean the sensors on these units?
I recommend vacuuming the sensor intake every 3 months. If dust builds up on the internal lens, your Home Assistant graphs will start showing “spikes” that aren’t actually there, which can trigger your automations unnecessarily.
Is it worth getting a unit with a PM2.5 display?
Absolutely. Having a physical display on the unit allows you to verify the air quality at a glance without opening an app. It also serves as a “sanity check” to ensure the data being sent to your smart home hub is accurate.
