A simpler media-filter upgrade can be a better fit than a major whole-home system. Sometimes simple works best.
We install whole-home air purifiers that mount in your ductwork and treat every room. No hype, no miracles—just honest advice on what works for Chicago air quality issues.
We're techs, not air purifier salespeople. Here's what each technology actually does—no upselling, no magic promises.
What it catches: Particles 0.3 microns and larger
Best for: Dust, pollen, pet dander, mold spores
Cost: $$ installed
Maintenance: Replace filter yearly ($)
Note: Most effective for allergy sufferers. Gold standard for particle removal.
What it kills: Bacteria, viruses, mold (on coils)
Best for: Indoor air quality concerns, post-COVID awareness
Cost: $$ installed
Maintenance: Replace bulb every 1-2 years ($)
Honest note: Kills germs on coil surfaces, NOT throughout whole house air. Only air passing very close to bulb gets UV exposure.
What it does: Breaks down VOCs, odors, smoke
Best for: Cooking odors, pet smells, smokers
Cost: $$$ installed
Maintenance: Minimal (cells last 2-5 years)
Note: Excellent for chemical and odor removal, not particles.
What it does: Charges particles, collects on plates
Best for: Fine particles, smoke
Cost: $$ installed
Maintenance: Clean plates monthly (DIY, $)
Downside: Can produce trace ozone. Clean plates religiously or performance drops.
What it catches: MERV 11-13 filtration
Best for: Budget option, better than standard filter
Cost: $$ installed
Maintenance: Replace every 6-12 months ($)
Bernie's Recommendation:
Most Chicago homes do fine with a MERV 11 media filter ($$ installed). Save the $$ unless you have specific allergies or asthma. This isn't technically an "air purifier" but it's 80% as effective for 25% the cost.
We're radically honest because we're not here to sell you the most expensive system. Here's what air purifiers won't do:
Air purifiers reduce airborne particles. They don't magicaly eliminate dust on surfaces or pet hair on furniture.
They reduce triggers, not eliminate them. If your allergic to dust mites, you'll still have reactions—just fewer of them.
Only air that passes very close to the bulb gets UV exposure. Theyre not whole-home sterilizers.
Air purifiers enhance good filtration, they don't replace it. Change your furnace filter regulary.
Expect 20-60% reduction in airborne particles depending on the system, how often your furnace runs, and ductwork quality. That's real, measurable improvement—not magic.
"Air purifiers help. They don't perform miracles. If a salesperson promises 'hospital-grade air,' run."

What we see in Chicago homes from Edgewater to Bridgeport, Rogers Park to Pilsen—and which air purifiers actually help:
Tree pollen in spring (March-May), grass pollen in summer. Worst months: April and June.
Best solution: HEPA filtration or MERV 13 media filter
Older Chicago bungalows with humid basements grow mold. Spores circulate through ductwork. Very common in North Center, Andersonville, and West Ridge.
Best solution: UV-C light (kills mold on coil) + HEPA (captures spores in air)
Chicagos construction boom means airborne particulates citywide. Demolition, road work, new builds. Especially noticable in Logan Square, Wicker Park, and Humboldt Park right now.
Best solution: HEPA or electronic air cleaner
Peak allergy season in Chicago. Ragweed counts spike in late summer/early fall.
Best solution: HEPA filtration (captures pollen particles)
Homes sealed tight for heating = cooking odors, pet dander, and VOCs get concentrated indoors. This happends all across Chicago but especialy in older bungalows.
Best solution: PCO system (for odors) + HEPA (for pet dander)
What actually happens when we install a whole-home air purifier:
Install in return duct near furnace. Requires cutting ductwork to mount housing.
Time: 1-2 hours labor
Mount in supply plenum or directly on evaporator coil.
Time: 1 hour labor
Requires 120V power. We run a dedicated circuit if you don't have an outlet nearby.
Extra cost: $ for electrical work if needed
Sometimes need to cut access panel for filter changes or maintenance.
Extra cost: $ for ductwork modifications
Measure static pressure before/after to ensure system airflow isn't restricted. Too much restriction damages your furnace.
Included in installation price
Total installed costs—equipment, labor, and testing. No hidden fees.
Bernies honest hierarchy by need—not by profit margin:
HEPA filtration—most effective for particles (dust, pollen, pet dander).
Cost: $$ installed
PCO system or carbon filters—break down VOCs and odors.
Cost: $$$ installed
UV-C light (kills on coil) + HEPA (captures spores in air).
Cost: $$$ installed (combination)
Media filter upgrade to MERV 11-13. Not technically a "purifier" but 80% as effective for 25% the cost.
Cost: $$ installed
Combination systems (HEPA + UV + PCO): $$$ installed
Only worth it if you have severe health issues, immune compromise, or specific medical recommendations. Otherwise, your spending money you don't need to spend.
Bernies Bottom Line:
"Most Chicago homes do fine with a MERV 11 media filter ($$ installed). Save the $$ unless you have specific allergies/asthma."
Sometimes a $ portable unit makes more sense than a $$ whole-home system. We'll be honest about both:
Brands:
Blueair, Coway, Levoit, Honeywell
Cost:
$$ (buy yourself at retail)
Coverage:
One room only
Noise:
Can be loud, especially on high settings
Maintenance:
Replace filters every 6-12 months
Best for: Single bedrooms, apartments, renters, or if you have allergies in one specific room (bedroom).
Installation:
Professional installation required
Cost:
$$$ installed
Coverage:
Treats entire house (every room with a vent)
Noise:
Silent (mounted in ductwork, not living space)
Maintenance:
Set-it-and-forget-it (annual filter changes)
Best for: Whole-home coverage, homeowners with allergies/asthma throughout the house, people who want silent operation.
Our advice: If you have one bedroom with allergies, buy a $ portable unit at Costco. If you want whole-home coverage and you own the place, install a duct-mounted system. We're techs, not air purifier salespeople—we'll tell you which makes sense.
For allergies/asthma: HEPA filtration (most effective for particles). For odors/cooking smells: PCO or carbon filters. For mold concerns: UV-C light + HEPA. Budget option: Media filter upgrade to MERV 11-13 ($$ installed). Most Chicago homes do fine with a MERV 11 media filter. Save the $$ unless you have specific allergies or asthma.
Total installed costs: Media filter upgrade: $$. UV-C light system: $$. HEPA system: $$. Ionizer/electronic: $$. PCO system: $$$. Annual maintenance costs range from $ depending on the system.
Air purifiers reduce airborne particles measurably (20-60% depending on system). They don't cure allergies—they reduce triggers, not eliminate them. Youll still need to dust and vacuum. If a salesperson promises "hospital-grade air," run. Air purifiers help. They don't perform miracles.
Media filters: Every 6-12 months ($). HEPA filters: Yearly ($). UV bulbs: Every 1-2 years ($). Electronic cleaners: Wash plates monthly (DIY, $). PCO cells: Last 2-5 years.
UV lights kill bacteria, viruses, and mold on coil surfaces where the light shines directly. They do NOT "purify all air" in your home—only air that passes very close to the bulb gets UV exposure. Theyre effective for preventing mold growth on your evaporator coil, but they're not a whole-home air sterilizer. Be wary of overselling.
Whole-home systems require cutting into ductwork, running 120V power, and testing static pressure to ensure your system isn't restricted. We don't recommend DIY. Improper installation can reduce airflow and damage your furnace. Professional installation takes 1-2 hours and costs $$$ depending on the system.
We'll help you choose the right air purifier for your needs and budget. Serving homes in Sauganash, Edison Park, Old Town, Uptown and all across Chicago. No overselling, no hype—just honest advice from Chicago techs since 1992.
Most consultations take 15-20 minutes. We'll measure your ductwork and recommend what fits your system.
