Introduction

The Xiaomi Smart Air Purifier 4 is one of the most popular air purifiers on the market today. As people become more aware of indoor air quality and its impact on health, devices that can help clean and circulate air have grown in demand. Let’s take a closer look at the features and performance of the Xiaomi Smart Air Purifier 4 to see if it lives up to its reputation as an affordable and effective air purifier.

Design and Setup

The Xiaomi Smart Air Purifier 4 has a clean, minimalist design that will fit in most home styles without looking out of place. It is cylindrical in shape and stands just over 25 inches tall. The all-white exterior gives it an understated look.

Setting up the air purifier is straightforward. You simply remove it from the box, attach the base, and plug it in. The included remote control takes standard AAA batteries. From there, you can power it on and connect it to the Xiaomi Home app via WiFi to control and monitor it from your phone.

The app walks you through the setup process. You’ll need to select your country and time zone. Then it detects the purifier on your network and pairs automatically. Through the app you can check status alerts, change modes, set schedules and more. Setup only takes a few minutes.

Filtration System

One of the key aspects of any air purifier is the filtration system. The Xiaomi Smart Air Purifier 4 uses a four-stage filtration process:

• Pre-Filter – Catches larger airborne particles like hair and dust. This outer layer protects the inner filters.

• Anti-Bacterial Filter – Infused with an antibacterial agent to capture and inhibit the growth of bacteria and other microbes in the air.

• VOC Filter – targets and removes volatile organic compounds (VOCs) from off-gassing furniture, cleaners, air fresheners and more that can reduce indoor air quality.

• True HEPA Filter – The innermost filter uses high-efficiency particulate absorbing (HEPA) technology to capture at least 99.97% of airborne particles 0.3 microns in size, including pollen, mold, smoke and other allergens.

Replacement filters should be changed every 6-12 months depending on usage and environment. Genuine Xiaomi filters can be purchased directly from their site or authorized sellers. Using non-OEM filters could compromise performance.

Operation Modes

The Xiaomi Smart Air Purifier 4 offers five operation modes to meet different indoor air cleaning needs:

• Auto – Automatically adjusts fan speed based on detected air quality. Ideal for set-it-and-forget-it operation.

• Sleep – Runs at low power and noise levels for use overnight.

• Favor – Boosts fan speed for 15 minutes to quickly freshen air before guests arrive or after cooking.

• Low – Runs the fan at minimal speed for quieter purification.

• High – Runs the fan at maximum speed for heavier filtering during pollution events like smoke or dust storms.

You control the mode via the remote or app. Timers and schedules can also be set so the purifier runs unattended as needed.

Sensor & Filtration Performance

To monitor indoor air quality, the Xiaomi Smart Air Purifier 4 contains a laser particle sensor that detects PM2.5, PM10 particulate matter as well as VOC levels. Readings are displayed on the front panel and through the app in real-time.

Independent air filtration tests have found the purifier highly effective at removing indoor air pollutants:

• Removes up to 99% of airborne particles and allergens including pollen, smoke and pet dander down to 0.3 microns in size.

• Reduces PM2.5 by up to 70% in a 158 square foot room within an hour on high speed setting – meeting WHO recommended safety standards.

• Lowers formaldehyde and benzene VOCs in the air by more than 90% on auto and high modes, far surpassing industry standards.

So performance wise, the combination of laser particle sensor, four-stage True HEPA filtration and ability to circulate air every 12 minutes makes it a capable choice for mid-sized rooms up to 500 square feet.

Smart Features & App Control

Perhaps one of the biggest selling points of the Xiaomi Smart Air Purifier 4 is its smart functionality and app control abilities via Xiaomi Home. Some key connected features include:

• Real-time Display of Air Quality Index – Check PM2.5, PM10, and VOC levels on the app from anywhere.

• Remote Control – Power on/off, change modes and set timers away from home.

• Filter Replacement Reminders – Get notified when it’s time to change filters to maintain performance.

• Weekly & Monthly Reports – See charts of historical air quality and purification metrics over time.

• Smart Notifications – Receive alerts for high pollution or purified air target achievements.

• Voice Control – Use voice assistants like Alexa for non-touch operation.

• Device Sharing – Authorize family or roommates with their own accounts to view stats.

• Firmware Updates – Push automatic or manual updates for new features and optimizations.

So connectivity takes an already effective standalone air purifier and enhances user experience through monitoring, remote functionality and personalized settings tailored to your schedule and home. This adds long-term value for those seeking smart home tech.

Value for Money

At around $300, the Xiaomi Smart Air Purifier 4 sits in the mid-range for premium air purifiers with advanced features. However, its strong point is the excellent value it offers considering included specs and performance:

• Military-grade True HEPA filtration that filters 99.97% of particles 0.3 microns or larger.

• Smart connectivity including app control, WiFi, remote and voice assistance add major convenience.

• Particle and VOC sensors that display real-time indoor air quality data.

• Auto mode automatically adjusts fan speed to optimize cleaning without manual adjustments.

• Filter replacements are reasonably priced direct from Xiaomi at $50-75 for a full set.

Compared to similar purified from competing brands with similar capabilities, the Xiaomi Smart Air Purifier 4 undercuts on price by $100-200 while delivering comparable if not better air cleaning results. Factor in the value of ongoing app updates and a growing smart home ecosystem, and value for money is excellent.

Potential Downsides

No product is without areas that could potentially be improved:

• App could use a redesign – interface feels dated and lacks certain features found in competitor apps.

• Limited voice assistant support – works with Alexa but not yet other popular assistants worldwide.

• Filter replacement reminder utility could be enhanced – currently only warns at 6 month intervals.

• Additional reporting metrics would be welcome – like historical ambient vs. purified air quality.

• Lacks WiFi connectivity when power is off – can’t check status remotely during power outages.

However, none of these are deal-breakers given the budget price point and core fan/filter performance which remains best in class. Over time, app enhancements are likely through continued firmware updates.

Should You Buy It?

In summary, if you’re looking for a capable air purifier with excellent value that also delivers smart home connectivity through WiFi and mobile control, the Xiaomi Smart Air Purifier 4 is a top choice:

• Proven True HEPA and multi-stage filtration to clean air in rooms up to 500 sq ft.

• Real-time monitoring of PM2.5, PM10 and VOC levels through a built-in sensor.

• Automatic and manual modes provide flexibility based on your schedule or changing conditions.

• Affordable pricing, reasonable replacement filter costs and added benefits of the growing Xiaomi Home ecosystem make it a smart long term investment.

• Occasional app/feature updates extend usefulness overtime without needing to replace the unit itself.

Especially for those seeking their first purifier or to add to other rooms cost-effectively, it delivers air cleaning muscle with nice smart features at an unbeatable value. So for the price point, the Xiaomi Smart Air Purifier 4 stands out as an easy recommendation.
