This air purifier home system offers a comprehensive solution for maintaining excellent indoor air quality and creating a healthier living environment.

First and foremost, the Core 600S features a solid-base design, deviating from the compact shape commonly found in air purifiers. This larger device is perfect for spacious areas but might not be suitable for small bedrooms. 

In fact, the Core 600S is approximately 30% bigger than its predecessor, the Core 400S. However, this emphasis on performance and simplicity over aesthetics is what truly makes this air purifier shine.

One of the standout features of the Core 600S is its utilization of VortexAir Technology, which ensures powerful air purification throughout your home. This technology, combined with the device’s top control panel, makes operating the air purifier a breeze. 

Weighing in at 13.6 lbs, the Core 600S is relatively lightweight, allowing for easy portability between different areas of your home.

Now, let’s talk about the core of the Core 600S: its 3-stage mechanical air filtration system. The pre-filter efficiently captures large particles like dust and pet fur, while the True HEPA filter takes care of allergens, pollen, and bacteria, promoting a healthier living environment. 

Additionally, the activated carbon filter eliminates stubborn cooking smells and pet odors, ensuring your home smells fresh and clean. What sets the Core 600S apart from its competitors is it’s all-in-one filter, which lasts longer thanks to HEPASmart technology.

In terms of performance, the Core 600S truly shines. It meets CARB standards and outperforms other mid-range air purifiers in terms of cleaning efficiency.

Now, let’s address the elephant in the room: noise levels. Thankfully, the Core 600S operates quietly at just 26 decibels in silent mode, ensuring a peaceful and undisturbed environment. 

However, if you opt for higher fan power, the noise level can reach around 55 decibels, which is still relatively tolerable considering its cleaning capabilities.

Levoit understands the importance of smart features in today’s connected world, and the Core 600S doesn’t disappoint. With its AirSight Plus technology, the air purifier intelligently senses the air quality and adjusts its performance accordingly. 

The Sleep Mode is perfect for nighttime use, as it keeps the purifier quiet and dim to ensure a restful sleep. The VeSync app takes convenience to another level, allowing you to control and monitor the air purifier remotely.

05- Alen BreatheSmart 75i – Best Whole House HEPA Filters for furnace

  • Sleek and visually appealing design with a selection of 14 color options.
  • Efficient air flow system optimizes fan power for effective purification.
  • Utilizes True HEPA filter capturing 99.97% of particles as small as 0.3 microns.
  • Offers four filter options to address specific air quality concerns.

  • Remarkable room coverage of up to 1300 square feet with 2X to 5X air changes per hour.
  • Operates quietly with noise levels as low as 25 decibels, aiding sleep and productivity.

Reasons To Avoid

  • Heavier compared to other Alen models, weighing 27 lbs.
  • Lack of 360-degree air intake found in some high-end devices.

Visually, the Alen BreatheSmart 75i closely resembles its predecessor, the BreatheSmart Classic, with a few notable differences. Firstly, it boasts a slightly larger size, standing at 27 inches compared to the previous model’s 26.7 inches. 

Additionally, the construction of the device features a more robust metal, giving it a luxurious appeal. With a stunning selection of 14 color options, the Alen BreatheSmart 75i adds a touch of elegance to any space, beautifully reflecting light and catching the eye.

The air flow system of the Alen BreatheSmart 75i remains consistent with the BreatheSmart Classic, adopting a bottom-to-top design with a sizable air filter located behind the front panel. 

While it may not have the 360-degree air intake found in other high-end devices, this system optimizes the efficiency of the fan power.

Although the design changes may seem subtle, a closer look reveals the main distinctions. The outlet air grill features a fresh appearance, and the modern control panel prominently displays the Alen BreatheSmart 75i logo, rather than just the word “BreatheSmart.”

In terms of weight, the Alen BreatheSmart 75i is the heaviest among Alen’s air purifiers, weighing 27 lbs. This is understandable considering the need for larger machines to accommodate powerful fans capable of drawing in more air. 

Comparable examples include the Blueair Classic 605 and IQAir HealthPro Plus, both weighing 35 lbs. Nevertheless, the Alen BreatheSmart 75i comes equipped with a convenient handle, ensuring hassle-free mobility around your home.

A critical factor to consider when evaluating the performance of an air purifier is the quantity and quality of its air filters. The Alen BreatheSmart 75i incorporates Alen’s signature 3-stage air cleaning system. 

However, what truly sets it apart is the utilization of a True HEPA filter. This powerful filter captures a remarkable 99.97% of particles as small as 0.3 microns, including dust, dust mites, pollen, and other pollutants.

The Alen BreatheSmart 75i offers four available air filter options to cater to specific air quality concerns. The Pure filter represents the standard True HEPA filter, efficiently capturing various pollutants. 

For those sensitive to volatile organic compounds (VOCs) and household odors, the Fresh filter combines the True HEPA filter with an Activated Carbon filter. 

The Pet filter utilizes Alen’s patented Molecular Conversion Powder to eliminate heavy pet odors at a molecular level, while the Heavy Odor filter tackles odors from everyday activities, such as smelly kids/teenagers and kitchen garbage.

Alen has maintained its successful air filtration formula with the Alen BreatheSmart 75i, incorporating a mesh pre-filter to capture larger particles and extend the lifespan of the True HEPA filter. 

The device also features an ionizer, which enhances the overall efficiency of the air filtration system. By releasing negatively-charged ions, the ionizer facilitates the trapping of allergens by the True HEPA filter. 

Moreover, the True HEPA filter is infused with an antimicrobial compound, protecting it from harmful bacteria and microbe growth.

According to our extensive research and testing, the True HEPA filter of the Alen BreatheSmart 75i surpasses that of other well-known brands, guaranteeing high-performance air purification. 

With an impressive capture rate of 99.97% for particles as small as 0.3 microns, including bacteria, this air purifier ensures a cleaner and healthier living environment.

With its whole house HEPA filters, you can effectively capture and remove airborne particles, allergens, and pollutants from your entire home.

Another standout feature of the Alen BreatheSmart 75i is its remarkable room coverage. With a capacity to purify spaces of up to 1300 square feet, this device surpasses all other models in the Alen lineup. 

By providing 2X to 5X air changes per hour, the Alen BreatheSmart 75i ensures the circulation of fresh, clean air in smaller rooms more frequently.

When it comes to air purifiers, the Clean Air Delivery Rate (CADR) is an essential metric to consider. The Alen BreatheSmart 75i boasts a CADR of 355 Dust/350 Smoke/400 Pollen (cfm), delivering an efficient air purification performance. 

However, it’s worth noting that the fan power, while commendable, may prove insufficient for the 1300 square feet room coverage. In such cases, we recommend using multiple units or considering a larger model, such as the Blueair Classic 605.

Despite its True HEPA filter and robust performance, the Alen BreatheSmart 75i operates quietly, even at its highest setting. With a noise level as low as 25 decibels at the lowest setting, this air purifier competes with the quietest devices on the market. 

Even at the highest setting, the noise level reaches only 49 decibels, quieter than a normal conversation. For added convenience, the Alen BreatheSmart 75i features a pink noise frequency, which aids in sleep and productivity.

In terms of additional features, the Alen BreatheSmart 75i includes a Smart Sensor that quickly and accurately detects air quality. 

Based on the detected air quality, the sensor automatically adjusts the fan speed, optimizing energy consumption. For a peaceful night’s rest, the device offers a lights-off mode, ensuring silent operation during bedtime. 

Other notable features include a timer, an LED indicator for filter replacement, and a child lock function for safety.

Overall, the Alen BreatheSmart 75i excels in providing reliable air purification and energy efficiency. Its true effectiveness lies in the high-performance True HEPA filter, room coverage, and exceptional noise levels. 

By combining these features with an array of customization options, Alen has successfully positioned the BreatheSmart 75i as the best whole house air purifier for the furnace in 2024.

This filter has been meticulously engineered to capture an impressive range of pollutants, including pollen, mold, bacteria, fungi, pet dander, dust, tobacco smoke, and even smog. 

Its exceptional filtration efficiency allows it to capture impurities as small as 0.3 microns, ensuring that the air you breathe is of the highest quality.

One key decision-making factor in the realm of whole house air purifiers is the ability to effectively clean large spaces. The Aprilaire 2410 shines in this aspect, as it is designed to clean rooms up to 2000 square feet with ease. 

Its integration with the whole-home HVAC system ensures that every corner of your house receives clean, purified air.

We were particularly impressed by the Aprilaire 2410’s cabinet design. It shares the same sturdy and corrosion-resistant pre-painted steel cabinet as the 1410 and 3410 models. 

This not only ensures durability but also contributes to the purifier’s sleek and modern appearance. Additionally, the Aprilaire 2410 features a proprietary door design and Self-Seal technology, effectively eliminating any unfiltered air bypass. This means that all the air passing through the purifier is thoroughly filtered, maximizing its efficiency.

Installation convenience is another notable advantage of the Aprilaire 2410. With its shorter height compared to previous models, it easily fits into limited spaces, making it suitable for various installation scenarios. 

Weighing in at just 17 lbs, it is lighter than the Aprilaire 2210, allowing for hassle-free handling and installation.

Let’s delve into the evolution of the Aprilaire 2410 from its predecessors. The incorporation of the MERV-13 air filter in this model sets it apart from the older cabinet models. 

This upgrade significantly enhances its pollutant-trapping capabilities, making it a compelling alternative for those seeking the highest level of air purification. 

The utilization of the same state-of-the-art filter media across the 2410, 3410, and 1410 models ensures consistent performance, providing peace of mind to homeowners.

While the Aprilaire 2410 boasts numerous benefits, it’s important to address one drawback: the absence of a thermostat. 

Unlike the Aprilaire 3410, the 2410 does not include a built-in thermostat and requires a separate purchase. Although this may be a minor inconvenience, it doesn’t detract from the overall excellence of the purifier.

In conclusion, the Aprilaire 2410 air purifier has exceeded our expectations and proves to be the best whole house air purifier for furnaces in 2024.

Types of Whole House Air Purifiers

Whole house air purifiers offer an efficient solution for filtering household air through the existing heating or central air-conditioning system. 

By installing these purifiers in the return-air ductwork, they capture particles and pollutants as the air passes through, ensuring that every room in the house benefits from cleaner and fresher air. 

Now, we will explore the four main types of whole house air purifiers available, their features, benefits, and considerations. 

Whether you’re seeking relief from allergies or aiming to improve overall indoor air quality, understanding these options will help you make an informed decision that aligns with your specific needs and preferences.

1. Flat Filters: Protecting the Furnace

Commonly found in forced-air furnaces, flat filters serve as a rudimentary air-filtration system. While they protect the furnace from large dust particles, they are not designed to block microscopic particles that can irritate lung tissue. 

Pleated filters, on the other hand, are a slightly better alternative. These filters are electrostatically charged to attract allergens like pollen and pet dander, providing improved filtration. 

Pleated filters should be changed every two to three months for optimal performance and cost around $15.

2. Extended Media Filters: Enhanced Filtration

Extended media filters offer a higher level of filtration compared to regular fiberglass filters. These boxy units contain an accordion-like pile of filtration media, making them more effective in capturing pollutants. 

Due to their design, professional installation is required to ensure proper integration with the ductwork. It is recommended to replace extended media filters annually, and their price, including installation, typically ranges from $400 to $600.

3. Electronic Filters: High-Tech Filtration

Electronic filters, also known as electrostatic precipitators, represent a high-tech solution for air purification. These units charge particles as air passes through them, causing the particles to be collected on oppositely charged collector plates. 

Electronic filters are particularly efficient at capturing small smoke particles that may bypass media filters. Unlike other filter types, electronic filters do not require replacement. 

However, cleaning the aluminum collector plates in soapy water every few months is necessary to maintain their efficiency. It’s important to note that electronic filters may produce trace amounts of ozone, which can be a lung irritant. 

The cost of electronic filters typically ranges from $600 to $1,000, and they require a 120-volt electrical outlet for operation.

4. Ultraviolet (UV) Filters: Germ Elimination

UV filters are add-ons to whole-house electronic precipitators and are primarily used for germ concerns. These filters utilize ultraviolet light to eliminate airborne bacteria and viruses, making them highly effective in germ-prone environments. 

UV filters do not prevent direct exposure to germs but can eliminate them if they reach the filter. Hospitals often use UV air filters in tuberculosis wards due to their proven effectiveness. 

The cost of UV filters ranges from an additional $400 to $800, depending on the specific model and installation requirements.

Can You Put An Air Purifier On Your Furnace?

By integrating an air purifier into your HVAC system, you can enjoy continuous and efficient air purification throughout your entire home. 

Whenever the HVAC system runs to heat or cool your home, the air purifier operates in tandem, ensuring that the air in every room is thoroughly cleaned. 

This approach eliminates the need for individual air purifiers in each room and provides a cost-effective solution for maintaining high indoor air quality.

Air purifiers designed for furnace integration are equipped with high-quality filters that effectively capture and remove a wide range of pollutants. 

These filters are typically installed in the return-air ductwork of your HVAC system, strategically positioned to intercept particles as air flows through. 

Common pollutants such as dust, pollen, pet dander, mold spores, and even microscopic airborne particles are efficiently trapped, preventing them from circulating back into your living spaces. 

As a result, you and your family can breathe cleaner and healthier air, reducing the risk of respiratory issues and allergies.

Individuals who suffer from allergies or asthma can particularly benefit from an air purifier integrated into the furnace. These purifiers effectively capture allergens and irritants that trigger allergic reactions or asthma attacks, providing relief and creating a more comfortable living environment. 

By removing these particles from the air, the risk of experiencing symptoms is significantly reduced, allowing allergy and asthma sufferers to breathe easier and enjoy a better quality of life.

Installing an air purifier on your furnace not only improves indoor air quality but also offers long-term cost savings. 

Instead of investing in multiple standalone air purifiers for each room, integrating a single unit into the HVAC system provides comprehensive coverage throughout the entire house. 

Additionally, furnace-integrated air purifiers typically require less maintenance compared to standalone units. 

Regular filter replacements are necessary to maintain optimal performance, but these are often less frequent and more convenient, as the purifier shares the same maintenance schedule as the HVAC system.

It is essential to consider certain factors when contemplating the installation of an air purifier on your furnace. Firstly, the size and capacity of the air purifier should be compatible with your HVAC system to ensure efficient operation. 

Secondly, it is recommended to seek professional installation to guarantee proper integration and alignment with your existing ductwork. 

HVAC technicians possess the necessary expertise to ensure a seamless installation and can offer guidance on selecting the right air purifier model for your specific needs.
