AI Verdict
This is a 200 CFM air purifier with smart app and voice control, best suited for rooms up to 300 sq ft, not the advertised 1690 sq ft.
This air purifier is a situational fit because its 200 CFM CADR is suitable for smaller rooms (around 200-300 sq ft) where its smart features and quiet sleep mode can be beneficial. However, the advertised 1690 sq ft coverage is unrealistic for effective air purification, and user feedback indicates poor performance against dust.
If you need effective purification for larger spaces, look for air purifiers with a CADR of at least 300-400 CFM for every 500 sq ft of coverage, ensuring 4-5 air changes per hour.

Pros
- Dual air intake structure enables faster air circulation for more efficient air exchange.
- Sleep mode operates at a quiet 23 Decibels, with display lights turning off via the app for undisturbed rest.
- Connects to the 'Havaworks' app for remote control of fan speeds, timers, and sleep mode.
- Compatible with Amazon Alexa and Google Assistant for hands-free voice commands.
- Integrated particle sensors detect air conditions to auto-adjust fan speeds, indicated by 3-color air quality lights (Green, Orange, Red).
- Equipped with a HEPA filter that captures airborne particles as tiny as 0.3 microns, effective for smoke and fine particulates.
Cons
- The advertised 1690 sq ft coverage is misleading for effective air purification, as its 200 CFM CADR provides less than 1 air change per hour in that space.
- Reported to be ineffective at removing dust particles from the air, with filters remaining clean even after 18 months of use.
- One user experienced fan rattling after 18 months, indicating potential long-term durability concerns.
- The product's actual effective coverage is significantly smaller than the stated 'up to 1690 sq ft'.
Dimension Scores
The 200 CFM CADR is low for the advertised 1690 sq ft, providing less than 1 ACH, and user reports indicate poor dust removal despite effectiveness with fine particulates.
The 'Havaworks' app, Alexa/Google Assistant compatibility, auto mode, and 3-color air quality indicator offer convenient and hands-free operation.
While it has FCC and CARB certifications, a user reported fan rattling after 18 months, suggesting average long-term durability.
No specific energy consumption data is provided, but its relatively low CADR suggests it won't be a power hog, placing it around category average.
Best For
- Bedrooms or small living areas (around 200-300 sq ft) where quiet operation is essential.
- Users prioritizing smart home integration with WiFi, Alexa, or Google Assistant.
- Individuals primarily concerned with removing smoke or fine airborne particulates from cooking or other sources.
Not Recommended For
- Large open-concept living spaces or rooms exceeding 300 sq ft that require consistent, effective air changes.
- Households with significant dust accumulation or pet dander issues, as it reportedly struggles with larger particles.
- Buyers expecting a robust, long-term solution without potential mechanical issues after extended use.
Watch Out For
- The 1690 sq ft coverage claim is highly optimistic; a 200 CFM CADR provides less than 1 air change per hour in a room of that size, making it ineffective for true purification.
- Despite having a HEPA filter, one user reported that the unit does not effectively pull dust out of the air, with the filter remaining clean even after 18 months.
- A user noted fan rattling after 18 months of ownership, suggesting a potential for mechanical failure over time.

What Buyers Say
The biggest head-scratcher here is the room coverage claim; one user even noted the box listed 228 sq ft, not 1690 sq ft, which is a massive difference and aligns with the 200 CFM CADR for effective purification. While it reportedly handles smoke and fine particulates well, users with pets or significant dust found it didn't pull dust from the air effectively, with filters staying surprisingly clean. The smart features like the app and voice control are consistently mentioned as convenient, and the quiet sleep mode is a plus for bedrooms. However, a fan rattling after 18 months points to potential longevity issues.
“Honestly, I bought this thing for my big living room because it said 1690 sq ft, but my old cheap one actually pulls more dust. It's okay for when I burn toast, but don't expect it to magically clean a huge space or get rid of all the dog hair. The app is cool though.”
Common Praise
- Effective at clearing smoke and fine particulates from cooking.
- Quiet operation in sleep mode at 23 Decibels.
- Smart app control for fan speeds, timers, and sleep mode is convenient.
- Voice control via Alexa and Google Assistant works seamlessly.
- Auto mode with PM2.5 sensor and color indicator is a useful feature.
Common Complaints
- Does not effectively remove dust particles from the air, even in homes with pets.
- The advertised 1690 sq ft coverage is highly inaccurate for effective air purification.
- Filters remain clean for extended periods, suggesting poor capture of larger particles like dust.
- Fan started rattling after 18 months of use for one owner.
Ownership Tips
- The filter indicator might not accurately reflect the need for replacement if the unit isn't capturing larger particles like dust effectively.
- Despite the large advertised coverage, it's more realistically suited for single rooms up to 300 sq ft for noticeable air quality improvement.
- The 'Havaworks' app is necessary to fully utilize features like turning off display lights in sleep mode.
- Long-term users might encounter mechanical noises like fan rattling after about a year and a half.

Buying Guide
When you're looking at air purifiers, don't just look at the square footage claim. That number often refers to a single air pass, not how many times the air in your room actually gets cleaned. What you really need to care about is the CADR (Clean Air Delivery Rate) and how many Air Changes Per Hour (ACH) it can provide for your specific room size. Aim for at least 4-5 ACH for effective purification.
CADR (Clean Air Delivery Rate)
This number tells you how quickly the purifier removes pollutants like smoke, dust, and pollen from the air. A higher CADR means faster cleaning, like a stronger vacuum for your air.
HEPA Filter
This is the workhorse for capturing tiny particles. It's like a super fine mesh that traps allergens, pet dander, and mold spores as small as 0.3 microns, preventing them from recirculating in your air.
Air Changes Per Hour (ACH)
This indicates how many times the entire volume of air in a room is filtered in one hour. For effective purification, especially for allergies or odors, you want a purifier that can achieve 4-5 ACH for your room size.
Alternatives
If this unit's coverage or dust performance isn't enough, search for models with a CADR of 300 CFM or higher for rooms over 500 sq ft, and look for specific mentions of multi-stage filtration including activated carbon for robust odor and VOC removal.
